14 best synthetic motor oils

Synthetic motor oils are lubricants specifically designed for use in internal combustion engines. They are composed of artificially created chemical compounds rather than being derived from crude oil like conventional motor oils.Here are some key points about synthetic motor oils:

  1. Base Oils: Synthetic motor oils are formulated using highly refined base oils, often polyalphaolefins (PAO), esters, or a combination of these. These base oils provide superior lubrication properties and stability over a wide temperature range.

  2. Performance Benefits: Synthetic motor oils offer several advantages over conventional mineral-based oils, including better high-temperature stability, improved low-temperature flow, reduced friction and wear, enhanced fuel economy, and increased resistance to oxidation and thermal breakdown.

  3. Extended Oil Change Intervals: Due to their superior performance characteristics, synthetic motor oils can often be used for longer intervals between oil changes compared to conventional oils. However, it's essential to follow the manufacturer's recommendations for your specific vehicle.

  4. Cold Weather Performance: Synthetic oils flow more easily at low temperatures, which is especially beneficial in cold climates. This property ensures that engine components receive adequate lubrication during startup in sub-zero conditions.

  5. Heat Resistance: Synthetic oils are more resistant to high temperatures, making them suitable for high-performance and turbocharged engines that generate more heat during operation.

  6. Reduced Sludge and Deposits: Synthetic oils are less prone to forming engine sludge and deposits, leading to cleaner engines and potentially longer engine life.

  7. Compatibility: Synthetic oils are generally compatible with conventional oils and can often be mixed without any issues. However, for optimal performance, it's best to use one type consistently.

  8. Cost: Synthetic motor oils tend to be more expensive than conventional oils. Still, many drivers find that the extended oil change intervals and potential fuel savings justify the higher upfront cost.

  9. Viscosity Grades: Synthetic motor oils are available in various viscosity grades to suit different engine requirements. Always refer to your vehicle's owner's manual to determine the correct viscosity for your engine.

  10. Manufacturer Recommendations: It's essential to follow the oil specifications and recommendations provided by your vehicle's manufacturer to ensure proper engine performance and warranty coverage.

In summary, synthetic motor oils offer several performance advantages over conventional oils, making them a popular choice for many drivers. However, it's crucial to choose the right oil viscosity and follow the manufacturer's guidelines for your specific vehicle to ensure optimal engine performance and longevity.

Unseen Damage That's Eating Away At Your Engine

Did you know that up to 75% of engine wear occurs during warm up? Most oils drain from critical engine parts when the engine is turned off and need time to reach the peak protection temperature when turned back on. And with most car trips lasting 20 minutes or less, engines are exposed to wear for most of the trip.

User questions & answers

Question: Does this oil meet VW's 502.00 / 505.00 spec
Answer: It's likely not going to be on the VW certified list. But, 502/505.00 does mirror ACEA A3/B4 a lot. In the older manuals, pre-longitudinal 1.8T oil sludge, the manual did give you options, saying it needed to meet 502.00/505.00, ACEA A3/B4, or API CF-4 (older TDI's).
Question: Does anyone have a virgin oil analysis to post? thank you
Answer: I hear that if you take the oil to confession, it can be re-virginated. That's what my wife told me right before we got married.
Question: Amazon doesn't make anything. So who really makes this oil
Answer: Warren makes Kirkland oil as well. When I went today, Costco was selling a box containing 2 of the 5 gallon jugs of full synthetic for $24.99, which is about half of what Bezos is charging for the exact same product. The Costco jugs say, "Manufactured by Warren Distribution, Inc." and says "DEXOS approved Gen-2" as well.
Question: Do you just add it to the gas or pour in the glovebox
Answer: Before adding oil to your gas tank make sure to check the blinker fuild level. If it's at the full mark you can safely add all 5 quarts of oil into your gas tank. With full synthetic you'll get better gas mileage! If you want to really crank up your engines preformance, the next time your at the gas station, pop the hood, unscrew the engine oil cap, and fill your engine up with 93 OCT until it overflows. Put the cap back on and your good to go! I've gained around 100HP in my 1996 Ford Taurus.

Answer: I have been using full synthetic oil in my 98 Silverado 5.7. I now have 364k miles with no engine issues at all. I'd recommend it for anything that takes 5w30
Question: Is this truly fully Synthetic or is it a synthetic blend? If it's fully synthetic - whats the advantage of Castrol EDGE Extended Performance 0W
Answer: SAE refers to the grading system. There are actually thicker Euro 5w-30 oils, but this is a thin 5w-30 for American and Asian cars. This particular blend is the latest additive formulation for GDI / turbo engines, it should be one of the best products on the market.
Question: is amazon motor oil apao
Answer: "Approved - GMdexos1™ supersedes GM-LL-A-025, GM6094M and GM4718M" This is indicated on the 5W-30 Castrol Edge High Mileage data sheet, dated 09Nov15. On their latest data sheet dated 20Sep17, this approved statement is no longer indicated. 1 quart size or 5 quart size makes no difference. If the product was made after 20Sep17 then it is not likely to be approved for engines requiring dexos1. I would safely assume the bottle labeling will reflect whether or not using this as a suitable substitute over dexos1 type oil is acceptable. The picture is old and will, or should, be changed so their is no confusion.
Question: Is this a group IV oil
Answer: Castol says it meets the spec, and Ford SVT has approved Castrol 5W50 for use in the GT500. I use this oil in my 2013 GT500.

User questions & answers

Question: It says it ships in 1 to 2 months. This can't be right is it
Answer: If you buy it from 166 auto you will yet it with in 2 days
Question: I drive only 2500 miles (severe driving) per year. Is 1.5 years (3750miles) OCI ok using PP or should I go by 1/2 year time interval
Answer: Few things to consider:1) Have you been running Synthetics in the car prior to this change or is this your first or 2nd synthetic change?2) How many miles on the car? (how old)The answer to the first 2 questions will determine how sluged up your engine is and if changing to a synthetic and waiting a year is a wise thing. For example, if your car is 5 years old and has 40k miles on it and you have been running only conventional then no, you should not wait a year on a synthetic. You should do the first two OCI's a short ones, 6 months or 1500 miles (whichever comes first). The first two OCI's will clean the sludge off the engine and most likely plug up the oil filter, so you will be running in a bypass mode.Now that we got that out of the way, then yeah you can keep it for a year and 2500 miles, I would not keep it for longer than a year due to condensation issues via season change. Synthetic oils are more resistant to acidification so they can last longer than 6 months in an engine but I would not go beyond a year. Also, that all depends how long you drive i.e. if you drive at lest 15 minutes with engine that reached it's operating temperature then you are ok, you have evaporated most of the condensation in the oil.The most important thing you should keep in mind is CHECK YOUR OIL if you are going to keep it for a year. You don't want to run low on it (just in case your engine eats the oil).
Question: anyone know if this is the oil specified for the RAM (or jeep) ecodiesel
Answer: No it's not. The ecodiesel engines now calls for 5-40 oil, not 5-30 anymore. Addendum cards have also been shipped to dealers which are to be added to owner's manuals. These cards recommend the use of synthetic 5W-40 engine oil that meets the FCA Material Standard MS-10902 and API CJ-4 specifications.
Question: Is this good oil for a 2015 Nissan XTERRA
Answer: It's terrific in my 2011 Xterra, and I routinely tow a 3700-pound trailer. I don't do oil analysis, so I can't say whether this oil holds up better than any other brand, but I can say for certain that my engine hasn't blown up yet.

User questions & answers

Question: Can this oil handle high temperature
Answer: I don't know what you feel high temperature means. I have used it in an engine that ran as high as 100C without loss of performance.
Question: Can I use it for a toyota corolla
Answer: I've only used this in my 2010 Corolla s
Question: so whats the differrence or benefit of this over the other castrols
Answer: It was the least expensive 0w/20 good quality oil I could find at the time. Good good reviews, so I got it.Not sure if it's any "better" than any other good oil. You might find more answers at that website that talks about engine oil...........I think it's "Bob is the oil guy" ..........or something like that.
Question: Is this a synthetic, conventional or blend, base oil product
Answer: Not truly. It is a group 3 "synthetic" that uses conventional oil and refines it (via processes like hydrocracking) and in the US can be called synthetic but like most synthetics which are group 3 could not be called synthetic in many other countries like Germany for example. Those oils need to be group 4 which use P.A.O. basestocks or group 5 which use Ester basestocks. By the way since this oil is mainly concerning itself with oil sticking to metal Ester basestocks are naturally excellent at adhering to metal surfaces. There are differences between group 4 and 5 oils. A major one is that Esters are hygroscopic (absorb water) while P.A.O. are hydrophobic (do not absorb water) in practical terms it could relate to seal swell. True synthetics have very consistent molecule structure an as such do not need V.I. additives to try to stabilize viscosity over time. True synthetics maintain that on their own. As should be obvious by now there is no simple answer to what is "best". I use group 3 synthetics in my street muscle cars. Companies have rebates multiple times a year for months. I take advantage of those. If the oil is not as cheap on Amazon the big W store has low prices. Right now one can buy Pennzoil Platinum Ultra (their best) for $20/5quart jug. The rebate is $10. A good price. Mobil 1 E.P. is $25 and a E.P. filter $9. The rebate for just the oil is $12. The rebate for oil and filter is $17. Another good deal. For my supersport motorcycles I use motorcycle specific Group 5 oils usually such as Motul 7100 (made in France). I urge everyone to learn about oils and be comfortable in their selections. Follow your vehicles manufacturers recommendations. If you read the fine print on any oil they pretty much make their claims then add to follow your manufacturers recommendations in oil specs and change intervals. We had a motor oil discussion here that went on over 4 years. The Bobstheoilguy site is still up and joining that is a great idea IMO

User questions & answers

Question: why bosh filters
Answer: I checked a virgin oil analysis for this oil, it showed no moly to speak of in the oil. Moly is typically what causes issues in a wet clutch system. I have used Castrol 0-30 in my wet clutch motorcycle and it performs very well. The formulation for the Castrol 0-30 and 0-40 appear to be very close, outside of the viscosity. The 0-30 is considered a "heavy" 30 weight the 0-40 is considered a "light" 40 weight. I would use this oil in my wet clutch applications.
Question: Doe's anyone know why this oil is so expensive
Answer: This is a full Synthetic, I believe the EDGE product line is always fully synthetic. The advantage of using to 0W-20 is usually improved fuel economy or gas mileage. Some newer import engines specify either 5W-20 or 0W-20, but if you can you should use 0W-20 as it generally reduces start-up friction compared to 5W-20. Some people are also using 0W-20 even if their engines call for 5W-30 for the benefit of reduced startup wear and improved fuel economy.
Question: Generally i use highmileage 5w-30 for my nissan sentra 2007 which has 200k miles, shall i use highmileage 10w-40 now
Answer: This Castrol oil has around 25% PAO in it's mix. Check out MSDS for a full breakdown.
Question: quisiera saber si es 10w30 o 10w40, la descripcion es diferente a la imagen
Answer: YES, it is Group IV. Response direct from Castrol: "We formulate using a number of high quality synthetic base oils to ensure high level, superior performance of the products and Group IV is in the Castrol EDGE 0W-40 formulation." Their response was from my email which directed them to the Amazon link of THIS oil. I run this in my E92 BMW M3, fyi.
