I just wanted to share my "Zero-Sludge" strategy for oil changes going forward.
I'll be changing my oil every 4,000 miles with PUP Synthetic (5 quart jug from Walmart) from now on, and changing my PCV valve every 30,000 miles.
I started the regiment with an engine flush (Liqui Moly) to clean out the engine first.
I think oil testing labs that are telling people with 10k oil change intervals that their oil is still good for another X thousand miles, are missing the point.
The amount of sludge in your engine is proportional to how many miles you go between oil changes.
Sludge is that gooey black thick formation all over the inside of your engine which clogs oil passageways and causes lower oil pressure which can really
harm an engine over the long term.
I read so many posts on BITOG about people that are so proud that they are going 7500, 10000, 12000, 15000 OCI's and testing labs saying their oil is still good.
The focus should not be on how long you can go without an oil change, but instead how clean is the inside of your engine.
Think about it this way. If you were going to buy a used car, would you prefer the previous owner did 3k to 4k oil changes, or 15k oil changes.
