I use to run valve 20w50 racing oil
and changed oil every other race. I
changed to mobil full syn. and changed
oil evry three races. this year I am
using valve 20w50 syn power. My oil
rep at work said I should be able to
go 5 races with out changing oil.

How often do you guys change your syn.

i also used to run valv. 20/50 and change every other race. now i run royal purple 15-40 and im gonna start out with 8 races. i change the filter every other night and check it inside to make sure its ok. got 5 nights on it now and the oil looks like new. just make sure you dont have problems like gas or alky in the oil and you should be fine going 6-8 nights.

Royal purple 15w40 here and I change it after 3 races(nights) filter every race(night).The oil and filters are donated if I was paying for it I would run it longer it is still transparent after 3 races.

5 nights at the track...8 lap heats and 15 or 20 lap features.

Thanks guys.

I was changing the syn. every three races
(nights) because it was dark colored. The
oil rep said that doesnt mean its dirty/
the combustion will turn it dark.

Do you think the filter should be changed
more often then the oil? I am using the
ac racing filter that filters smaller particals.
