Pre-purchase inspection - what do you guys think?

[luvrbus]

I hope it works out for you,it is hard to do a oil test without a previous test to compare with the latest test ,you have no idea what oil was used, miles on the oil, was the oil mixed brands, and cheap oil filters the glue used can cause a high potassium, labs can do you a cut filter analysis they show a lot that sometimes does not show up on a regular oil sample analysis, I always found CAT to be the best for fluid sampling. Another option is take the bus to a CAT dealer and spend a 1000 bucks for an inspection, I have had the C-10 and C-12 last for over 20,000 hours with just minor problems working in conditions where we would change the air filters every 2 days
