When you buy sunoco make sure it's not methanol

[Lyn Smith]

I have purchased Sunoco from more than 15 different vendors over the years.Have never had a problem with Purple, or the Blue that I use now.I have left it in my fuel cell and it still checks 6 months later.Just recently I had some C11 VP that I tried at Indy to help me qualify because I was told it was faster.Made 2 runs at St. louis points race and changed back to my $8. a gallon Sunoco Blue.Car ran the same with both fuels.The only problem I have heard with any of the fuels, is that some dealers are not using new drums when they pick up their fuel.Now Sunoco requires the use of new drums for all the fuels.

You may not have realized the full benefit of C-11.The conventional wisdom among experienced C-11 users is that to be fast with it, you'll have to retard the ignition timing a couple of degrees and go up a couple of jet sizes. I don't know if a straight switch from Purple or Blue to C-11 (changing nothing else) would allow you to see all there might be to see.

OK. The lesson here is....may the buyer beware! Time to put it to bed.

I've got to admit my curiosity is up a little, I plan to put this to the test this winter on the dyno. Maybe I will report back on this, PR maybe I won't 😆

This thread is unbelievable !!! How on earth couldn't you know the difference?? Doesn't gas smell like gas ?? Time to get back on your 85b and mill off your intake flange and get a new block and heads that never came on your car !! Haha !!

I run C11 and this is exactly what I have had to do! Low compression (at least (mopars) motors seem to run better on the dyno and the track like this.

1320racer, exactly how successful are you with your 3 cars and combos after 3 decades? You say everyone knows you? I've been Drag Racing over 5 decades and I've never heard of you. Your lack of respect to other racers here and your ego tells me I could care less to meet you. Jim

never heard of you either and also couldn't care any less about your comments..

I'll just say this.. if you are actually trying different fuels, and not making tune-up changes according to what your combination wants for that particular fuel, you just may be missing the advantages to that fuel.. and it is easier to do it on the dyno, if you in fact dyno.. many do not, because they run the same combinations freshen up after freshen up.. so they would have to try it at the track... and believe me, O2 sensors make the difference.. it's not that easy to read spark plugs anymore with some of these fuels..

There are some fuels that are almost a direct change over, but even with those, a little tuning would make things better..
