For the price of two quarts of the Red Line you've been using you can buy a five quart jug of M1 15W-50. You could drain the oil twice as often and still come out ahead.
A UOA interpreted by someone who knows what he's looking at would probably be a wise investment for you.
Have one done and post it here. Somebody with some knowledge is bound to comment in a reply.
Well yes and no ... Redline has a huge "laboratory" of racers out there building extreme engines and beating the living snot out of the oil. Literally, thousands of weekend drag racers and track guys are out every weekend all over the country killing engines and Redline hears a lot about what works and what does not.
It's not XOM's labs, but it may actually be better ... It's pitting their oil against real world conditions that may never come up in a lab situation. Rain delays and 95% humidity with alcohol fueled motors. Scorching hot track days. Off road dust and dirt. Salt air and marine environments. All kinds of misfires and fuel dilution with all kinds of fuels.
I suspect Redline knows more about fuel dilution handling than almost anyone on the planet.
And they are also literally a stones throw from the most modern refinery in Calif that was built by XOM a while back, before it was sold (Kalifornia Liability exposure ...). Chevron is maybe 45 minutes away. SOPUS Martinez is 10 minutes away. And the Redline engineers play golf with the big boy engineers, so they know what's up over there too
Saying all that, do I think it's the best oil - maybe, but prolly not. I run Motul 300V Ester if I want the best. It has worked for me in tough motor situations. But it's even more expensive here in the USA than Redline.
But I know race teams that buy Redline oil by the 55 gallon drum and won't run anything else. They'll just kick you out of their pit if you try to talk them into something else. And these guys are no slouches. They occasionally hold MPH or Lo ET records during the season and have done that on and off for many seasons ...
You takes your pick, and you spends your money, and you run it till it blows
