Red Armor only 2 applications racing Drag sleds in snowmobiling when it 1st came out . 2nd in a 357 xp that I ported & ran 50:1 during its initial break in , so a few tanks . I then went with Interceptor at 40:1 for 3 yrs , most recently have switch to Dominator @ 44:1 with a fat tune . Dominator , my cost $48 Cdn. a gallon so Red Armor @ $50 USD. is a consideration for my 660 Milling saw . What does the cost in Ca. have any relativity ? P.S. Even at $60 USD. at todays price index for a Certified FD oil it's a consideration to me !
