How to Choose the Best 10W-20 Oil
Finding the right 10W-20 oil can feel like a niche task, but for those of us with older vehicles or specific small engines that call for it, it’s a necessary one. I spend a lot of time on the Bob Is The Oil Guy (BITOG) forum, which is a fantastic resource for this kind of deep dive into lubricants. The consensus there isn’t about a single “best” oil, but about matching the oil’s characteristics to your engine’s specific needs. The first thing I always check is the manufacturer’s manual. If it explicitly recommends 10W-20, that’s your starting point. Don’t just guess; using the wrong viscosity can lead to poor lubrication or increased wear.
Once you’ve confirmed 10W-20 is correct, the next step is understanding the oil’s formulation. On BITOG, members often discuss conventional (mineral) oils versus synthetic blends or full synthetics. For older engines designed decades ago, a high-quality conventional oil is often perfectly adequate and what was originally specified. However, a synthetic blend can offer better protection during cold starts and under high temperatures, which is a common upgrade discussed by forum users. Full synthetics provide the highest level of protection and stability, but for some classic car engines, they can be overkill or, in rare cases, lead to leaks if the engine has become accustomed to conventional oil.
Another critical factor is the API service rating. This is a stamp on the bottle that tells you the oil’s performance level. For a 10W-20 oil, you’re likely looking for something like API SN or SP for gasoline engines. This rating ensures the oil has the necessary detergents and anti-wear additives to keep your engine clean and protected. The folks on BITOG are meticulous about checking these ratings to ensure compatibility, especially with older emission systems or specific engine components like flat-tappet camshafts that need extra zinc (ZDDP) for protection.
Finally, consider the brand reputation and specific use case. Through reading countless threads, I see certain brands consistently praised for their quality control and robust additive packages. The best 10W-20 oil recommendations from Bob Is The Oil Guy forum often point towards established brands that have been producing this viscosity for a long time, as they have the experience and formulation history you can trust. It’s not just about the brand name, but about finding a product that has a proven track record in engines like yours.
FAQ
Is 10W-20 oil still available to buy?
Yes, it is still available, but it’s not as common as 5W-30 or 10W-30. You won’t typically find it on the shelf at every local auto parts store. Your best bet is to check with specialized automotive shops, online retailers like Amazon, or directly from manufacturers that cater to classic car or small engine communities. The Bob Is The Oil Guy forum often has threads where users share direct links to online sources where they successfully purchased it.
My car’s manual says 10W-20, but I can only find 10W-30. Can I use that instead?
This is a very common question. While 10W-30 is a close neighbor, it’s generally not recommended to deviate from the manufacturer’s specified viscosity without consulting a professional. The 10W-20 was chosen by the engineers for a reason, likely to ensure optimal oil pressure and flow in specific clearances within your engine. Using a thicker 10W-30 could lead to slightly higher oil pressure but potentially less efficient flow at startup. It’s best to try and source the correct 10W-20.
What’s the main difference between conventional and synthetic 10W-20 oil?
The core difference lies in the base oil and its molecular structure. Conventional 10W-20 is refined from crude oil, while synthetic is chemically engineered to have more uniform molecules. This gives synthetic oil better performance in extreme temperatures—it flows more easily in cold weather for better startup protection and resists breaking down under intense heat. For a daily-driven classic car, a synthetic might offer an extra margin of safety.
Why do some older engines specifically require 10W-20 oil?
Engine design and manufacturing tolerances have changed over the years. Older engines often had wider bearing clearances and different oil pump designs. The 10W-20 viscosity was engineered to create the perfect oil pressure and film strength for those specific mechanical setups. Using a modern, thinner oil might not build sufficient pressure, while a thicker oil might not flow quickly enough to all parts, leading to wear. That’s why following the original specification is so important.
Are there any specific brands of 10W-20 oil that are highly recommended?
Based on discussions I’ve seen, there are a few brands that consistently receive positive feedback for their 10W-20 formulations. While I won’t single out one as the absolute best, looking at the best 10W-20 oil recommendations from Bob Is The Oil Guy forum will point you towards manufacturers known for their dedication to older engine oils and high-quality additive packages. These are often companies that specialize in lubricants for the classic car and marine industries.
How often should I change my 10W-20 oil?
The change interval depends heavily on the type of oil (conventional vs. synthetic) and your driving conditions. For a conventional 10W-20 in an older vehicle, following the classic 3,000-mile or 3-month interval is a safe and conservative practice. If you’re using a high-quality synthetic blend or full synthetic, you might be able to extend that, but it’s wise to check your oil level and condition regularly. Severe driving, like frequent short trips or dusty environments, warrants more frequent changes regardless of the oil type.
