dirt track oil question

[Indiana79]

This upcomming spring I will have 3 chevy 350 dirt track engines running our local track in the road runner class. "which is basically the entry level class" Last year we drained the oil (vr1 20w-50) about every 2 races due to the extreme dusty conditions. my question is after viewing some of the virgin vr1 oil samples its seams to be a very bland oil, ect no moly or not much boron "even some lack luster zinc and phos levels". Does anyone think it would be wise to ad an additive like schaeffers132, or go with a more robuse oil like maxlife and ad somthing to boost the zddp? With the frequent oil changes its kinda out of the questioin to run somthing expensive like redline for just two races in this division, but I want my motors protected as much as I can.

Mobil 1 15w50. Good ZDDP and will hold up in high rev engines. Easy to find and not that expensive.

Any of the HDEO such as delvac, delo,rotella will also do very well for you.

would their be any issues with the hdeo at high rpm's such as the one race car gets up into the 7000 rpm range on the straight aways... does anyone feel the lack of friction modifiers would have an ill effect at such high rpm? The price is one definate plus though especially for the short oci we run

check out the Dominator line by Amsoil.

Holds up well and has a nice additive profile.
