Even with the right oil, questions and minor issues can arise. Here are some common concerns related to amsoil 5w20 vs 5w30 choices.
Can I Mix AMSOIL 5W-20 and 5W-30?
While AMSOIL products are compatible with other synthetic and conventional oils, mixing different viscosities is generally not recommended. It dilutes the specific properties of each oil, potentially compromising the optimal performance and protection your engine requires. Stick to one viscosity for best results.
What if I Accidentally Used the Wrong Viscosity?
If you’ve accidentally used 5W-20 instead of 5W-30 (or vice-versa) for a short period, especially if it’s AMSOIL, your engine is likely fine. Modern oils are robust. However, it’s best to perform an oil change to the correct viscosity as soon as practically possible. Prolonged use of the wrong viscosity can lead to suboptimal lubrication or fuel economy.
Will Switching to AMSOIL Cause Leaks in an Older Engine?
This is a common myth. AMSOIL, like other high-quality synthetics, will not *cause* leaks. If an older engine develops leaks after switching to synthetic, it’s typically because the synthetic oil is doing its job by cleaning out sludge and deposits that were previously plugging existing, minor leaks. The synthetic oil’s superior cleaning action reveals pre-existing issues. Address the leak, don’t blame the oil.
My Engine Sounds Different After Switching – Is That Normal?
Sometimes, an engine can sound slightly different after an oil change, especially when switching to a higher-quality synthetic. This might be due to the oil’s superior lubricating properties reducing friction differently. If the sound is concerning (e.g., knocking, excessive ticking), have it checked immediately. Otherwise, a subtle change in engine acoustics is usually nothing to worry about.
