Is this ok for the o2 sensors

 

Read the links posted on previous pages, if it was harmfull to our cars they would've been trashed long ago. It's already in premium & race fuel. the key is to follow the guidelines and not go overboard. Kind of like steroids, if you follow a Dr's advice and are in good health, you typically won't have issues, but most people figure if 2 pills are good then 4 are better.
I wouldn't exceed 30% total Toluene. You can take your 14 gal tank & simply didvide it by 10,20 or 30%.
Again, read the links provided, they're for your benifit. I can't see how it could hurt your 02 sensor as long as you are reasonable.

 

Very true. I might do some asking around here on post.

 

i use the nos octane boost it says mix with minimum of 8 gallons to get around 6 full octane numbers

 

anyone ever tried methylcyclopentadienyl manganese tricarbonyl - MMT for boosting octane?

 

That's what's in the Torco product, and anything else that actually works. Essentially all the commercial MMT in the world comes from one source: Ethyl Corp., or its sister Afton Chemical, so everyone sells exactly the same product.

I would stay away from MMT based products! Here's a quote from an article on octane boosting :Unleaded racing gasoline may still contain damaging octane boosters like "MMT" or methanol. A very high alcohol content will lead to fuel line erosion, accelerated fuel pump wear, very poor fuel economy and possibly lower performance, as alcohols have a less impressive MON rating than aromatics.

MMT may cause problems. Personally I wouldn't use it but several people here have and seem to be OK with it. It's used in many parts of the world at the refinery for octane trimming. It's not used in the US. Canada is trying to phase it out but Ethyl is suing under NAFTA.

I'm not sure if you're confusing MMT with alcohol, though, you kind of switched gears. Alcohols do have a high "sensitivity," the difference between RON and MON, but the MON is still pretty good. They have a very high RON because under those conditions their high heat of vaporisation cools the charge.
