should I be using conventional oil or synthetic? My main goal is to prevent the car from throwing a rod through the block or something. I’m fine with putting in the oil but I can’t have this engine destroy itself. Will synthetic stop gunk up from happening? Should I be using a lighter (5w-20) or heavier weight oil (10w-40)? I feel that the heavier weight oil will slow down oil consumption but oil won’t be getting to necessary parts of the engine. What do you think?
The car doesn’t have a cat anymore
Also if there is a number I can call you at. I’d rather do that then text lol. Up to you though. If so, direct message me ur number
We use esters in our Engine Cleaner that should ultimately clean up the rings and pistons. The challenge in your situation is the consumption. For the best results you would add the cleaner at 1:5 ratio with the oil. The oil you are using is fine. As you add makeup oil you would need to make sure you top off the engine cleaner at the same rate to maintain the ester concentration.
An additional thought after looking at the pistons in the picture above would be to run a PEA based fuel system cleaner in your tank. I would probably do that continually for a couple thousand miles. Avoid the “Italian tune up” as EGT’s over 500f will kill the PEA.
This would be a slow and safe method for you to follow.
