Thanks for the advice… So I had it checked today by another car shop, (the cylinder compression ratios were 190, 195 195 190… ) and they said it was fine, the oil that they drained was fine, and that it sounded good too (could be my imagination trying to pick up noises, as it’s obvious from my dilemma; I do not know much about cars). I don’t add oil between oil changes and as I said above the other car shop said it was fine. So I imagine I’m in the clear until major noises come up again (the shop said clicking, knocking, metal on metal sounds) ?
Once again thanks for all the advice.
