call me a cheap skate- but i don't want to spend 23.00 bucks or up of an oil analysis. i don't live near a big rig shop,etc where i could drop it off for a cheaper price. the cheapest i could find online was for 14.95 from a company called http://www.vehicare.com/oilcheck.htm- but i have seen any members using them. anybody using a reputable company that is charging a reasonable price-like 14.00 to 18.00 bucks.

 

I have mine done by blackstone labs, I bought 6 at a time and they are $17 each.

 

I bought RP kits a few years ago for $7.50 and I think Schaeffers kits are about the same. I don't know if they will do the analysis if you send another brand lube to them in their kit. Craig
