What happens if you stop using synthetic oil?
Answer. Synthetic oils typically provide better protection than conventional oils, but switching back and forth between full synthetic and conventional oil will not damage the engine. Of course, this depends on the current engine condition and the quality of the conventional oil being used.
What kind of oil should I use for valve lifter noise?
Synthetic oil manufacturers often issue a warning about valve lifter noise when using synthetic in an older engine. If I were you, I would go back to a regular 5W30 mineral oil for one oil change to see if it improves.
Why does my valve lifter make a clattering noise?
Most engines with hydraulic valve lifters make some clattering noise during warmup. This is rather harmless, unless it persist after the a few minutes and when warmed up. Yes, an equivalent 5W30 dino oil is thicker than synthetic at very low tempertures (they are equal at 0 Celsius), and flows slower.
What makes the valve lifter noise in a Chevy 350?
If the engine is quite worn, and has large clearances, the 0W30 might make it WORSE, since this stuff is extremely thin and slippery. Synthetic oil manufacturers often issue a warning about valve lifter noise when using synthetic in an older engine.
Do you have to use Mobil 1 synthetic oil?
After that, you can rest assured that Mobil 1 synthetic oil is continuing to keep your engine running clean and well lubricated for mile after mile. Do I have to use the Mobil 1™ Extended Performance oil filter with Mobil 1™ Annual Protection motor oil for my engine to be covered under the limited warranty?

Which is better 5W30 Dino oil or synthetic oil?
Yes, an equivalent 5W30 dino oil is thicker than synthetic at very low tempertures (they are equal at 0 Celsius), and flows slower. So your 5W30 synthetic is probably the best compromise. If it takes only a minute or so for the noise to disappear, you’re OK, the engine is not in danger.
