How do I know what oil my car takes?
There’s no substitute for reading your owner’s manual. It will list what type of oil the automaker recommends for your car. It may also recommend different oil depending on whether you live in a hot or cold climate. The most important thing is to use oil that’s the right thickness, or viscosity, for your car’s engine.
What is the best oil for an old engine?
Valvoline MaxLife 10W-40 stands out as the best oil for old motors. Valvoline comes with enhanced additives. The additives enable your motor to perform better. It comes with seal conditioners that prevent leaks.
Can you use full synthetic oil in older cars?
Yes, you can use synthetic oil in your classic car. Synthetic oils are composed of chemically engineered molecules designed to provide higher performance and better protection for your engine than conventional oils, which are derived from crude oil without significant intervention from chemical engineers.
Should I change my oil based on time or mileage?
The general recommendation is to change your oil every 3,000 to 5,000 miles or every three to six months, with twice a year being the minimum.
Does Castrol GTX have ZDDP?
Castrol motor oil contains a zinc compound, zinc dialkyl dithiophosphate(ZDDP). This oil additive provides better anti-wear protection in your engine, especially the high load areas like the camshaft and lifters. Current standards have reduced the level of this additive below what it was in the past.
Should you use thicker oil in an older engine?
You should switch to thicker oil if your older car is consuming oil. The general rule is to always use the viscosity your car manufacturer recommended. As your engine gets older, the clearances within the engine change due to wear and tear, and your car could start to consume oil.

Should I use synthetic oil in my high mileage car?
