Running diesel oil

[dudemaaan]

Ash content would be less of an issue if running aux injection since the engine is always being steam cleaned. I had been running mobile 1 15/w50 which was designed for performance cars that needed extra antiwear additives. I'm not sure what the ash content was but it seemed like the oils with extra antiwear had more ash. Walmart stopped carrying the oil i used and it seems like all the oil formulas are going green which have much lower antiwear properties. These oils could cause us to see more bearing problems pop up. Not to mention our expensive turbos can use a good quality oil. At least the desiel oils don't appear to be removing all the stuff giving extra protection. I'm still debating on what oil i want to use. I like synthetic because it seems to run a little cooler, and doesnt coke up the turbo bearings. But it's also more expensive, so it may be just as well to go back to "dino" oil and change it twice as often. So many choices. If you google it, you'll see the topic of antiwear additives is an issue on tons of car forums.
