Hi, I don't understand how Red Line could destroy cats. and O2 sensors. Please elaborate further. Sounds fishy to me.quote:

However, in his Showroom Stock Mazdas, the use of Redline was eating through catalytic converters and O2 sensors (same in the World Challenge cars, actually) which may cause problems in street cars over a long period of time.

I have to extend the valid question MF150 asked.quote:

I know one of the experts on here has done some testing with tear downs and measurements and found Redline showed no increase in wear, despite UOAs showing more wear for the Redline sample.quote:
Ask him the difference in wear and engine cleanliness seen between Redline and Valvoline
Well if the Redline has ultra low oil consumption, it will probably cause LESS poisoning than other oils.quote:

I've used Redline 10w-30 in my truck and it seems to run pretty well on it. I'm a little apprehensive about the high phosphorous and zinc levels in it and their supposed poisoning of catalytic converters. The formulation looks like it would make a really tough racing oil for sure. I do like to add a quart of it to a batch of Mobil 1 to bring the additive levels up a bit. Has anyone here actually had a converter go bad from a motor oil?
I'm glad we agree on this point, and this has come up in the articles in industry magazines on drafting new standards.quote:

Exactly. If you look at Amsoil and Redline, two oils with more ZDP then most, their Noak volatility ratins are at 5%-6%. So very little burn off is going to occur so it's really not an issue.
