[QUOTE="Swiss Boss, post: 14262348, member: 153050"] Thanks Grant for finding a lab that will test HT/HS but it's a little expensive for my blood. Plus it seems they've got good explanation how they test it. Didn't have time to read though. As for the 10w40 on the track, I'll probably switch to the 20w50 as last Saturday my car overheat for the first time (250+CHT) and saw oil pressure as low as 60PSI @WOT. Still 25PSI @ idle when coming off track. Weather was like 85F and 80-90% humidity (Indiana) [/QUOTE]
