Because I don't have much time, I get my oil changed at "Fast Lane". They know me and my car, and they do a killer job.Natural Hi said:I tried Royal purple for the first time at the begining of the year. My engine is running smoothly, so I just bought a case for my next oil change. I found a supplier who I can get it for 4.36 a quart. What do you use?
thats good info.the test i saw before was a ls1 disassembled and every tolerance measured.the motor had very little wear and was nowhere even close to needing a rebuild.thats after 200,000 miles.mga said:
