Hi,
Just a quick one. I was searching for a previous answer to this question but could not find in the forum. I have a 1979 vet, 350 engine.

What type of petrol does everyone use. I was using 98 and was advised 95 would be better for the motor and there wasn't a noticeable difference in performance. Are there any other opinions?

Cheers Lefty :what: :what: :what: :what: :what: :what: :what:

Iuse 98, but not Shell fuel my car goes onto 7 cylinders. Other members have had the same problem.

I concur.  The Shell fuel seems to create havoc with carby fed engines.  I'm no fuel expert but I would say in depends on the compression of your engine.  My Vette runs 11:1 compression and a bit of a cam.  I have run it on 95 when I've had no choice but If I get into it it will ping it's head off.  I would guess that if you motor is a lower compression unit it would be ok on 95.

I was reading the for mum post http://nswcorvettes.com.au/forum/index.php/topic,3450.msg1045912742.html#msg1045912742

Which I think was one of yours cam, from BP. This was interesting, the recent issue I had with the hesitation could be put down to using 98.

I wonder if there is a fuel supplier out there who provides suitable fuel for our engines?

I use Caltex 98 in my 454. The previous owner warned me against using Shell V-Power as the engine definitely doesn't like it.

I've heard some reports of Vette engines running a tad hot when using 95.

If the engine is in good condition and good tune, then you should get better economy on 98 than 95.

(Economy is not something I bother about. I use a tankful on a day out anyway LOL!)
