RE: GAS


The higher the octane, the better, if in doubt, please contact your chemical engineer.

RE: GAS

Let's all agree to put in what the manual tells us.

And now a new gas issue...

I suggest to everyone buying BP gas. BP has some of the cleanest burning fuels and spends the most money of the major oil companies on researching cleaner gasses and the most environmentally friendly ways of digging for oil.

Also, the BP where I buy gas is significantly lower priced than the Chevron and Shell stations across the street. (Sometimes $1.85 vs $1.95 super--Ah, I love living in Texas...cheap gas! All you other suckers are paying $2.00+).

A true "Brit" here? Oh, I'm sorry, "Beyond Petroleum", not, "British Petroleum."

If your local chem eng told you that, he's either not a chem eng or has never really studied this issue. We could cut the chem eng some slack if he is located in a region that uses RON only instead of (R+M)/2 like the UK, and is referring to that case. Without giving a reason why, it is still not a good generalization. There is no reason to use an octane above one that already meets or exceeds the requirement stated in your manual - although in some regions where RON is used, there might be an exception related to the the "octane" stability.

BP? Haven't heard that one for quite a while. Don't have them in SoCal. In the late '80's, it was ARCO that had patents on the cleanest formula - which they licensed - and the cheapest fuel. One of the things that seems to confuse the discussion of octane are things that do not necessarily affect octane rating, like additives for cleaning. Chevron not too many years ago advertised Techron as only being available in their highest grade of fuel and recommending running 2 tanks of it to "clean your engine". Had nothing to do with the octane rating but it did add to the myth that higher octane fuels burn cleaner or clean better even if your car didn't require that grade. Now Techron is in all of their fuels so their is no reason to use the highest grade if your car doesn't need it.

RE: GAS

This is from the article that I posted about gas. The Honda lost power with premium gas.

The Accord took a tiny step backward in power (minus 2.6 percent) and performance (minus 1.5 percent) on premium fuel
