The great Optimax experiment

[NotoriousREV]

Well, the result are in. I tried Shell Optimax for 3 tankfuls, then switched back to normal unleaded for a tank to see what the differences were.

The result: I'm about £8 worse off than I would have been.

No noticable increase in performance, no improvement in economy.

Keep your money in your pockets.

Disclaimer: other vehickes may well prefer Optimax, this was a highly unscientific experiment and does not represent the views of the site owners, members, or (strangely enough) the author. :D

Will maybe be able to participate in this type of test in a year or so, Optimax has not reached this far north yet!

think it would work sweet in mine as mine is tuned for 100ron

What a stout fellow- we'll have a whip-round for the £8 when we meet!:smilegrin:

[superchargedmorph]

I only use it because of compressor. However when I researched the fact it is stated that with a supercharger you have to use the highest octane fuel you can get.

I'd reccommend it in yours, you'll probably find the cost evens out. Certainly wouldn't hurt to try it.

We'll call it a pint and a bag of pork scratchings :P

Thats a bit suspect, what if the highest you can get is 95, do they recomend octane booster?

[superchargedmorph]

yes they do, but compressors were in their hight a few years ago when fuel ratings were higher.

[Steve]

is there additives you can get to higher the octane??

Or am i being silly??

[brn7y]

Yes there are aditive that you put into the tank when you fill up.

Try this for some info.

i guess optimax is cheaper in the long run??

just a pain in thre A*$ to travel miles to get a tank full of fuel.. as shell are not in my part of town :smilegrin:

[Steve]

Ok.. i have for the first time used Optimax. Simce my car is tuned for 100 ron guess it would be the nearest suited fuel.

I think i have already noticed a difference. The engie on tickover does not seem to be so tappy anymore and alot quieter... i will investigate this further. It might of been because i was using 95ron that the idle was crap.

Who knows... i am not a mechanic :smug:

Have you tried 98 octane, i used to run the Scooby on that

[Steve]

optimax is 98.3

[Monster-Mat]

99 octane:smilegrin:

[Steve]

i read on the pump 98.3

[NotoriousREV]

you'll find Optimax is cheaper than other garages high octane fuel too.

Definately sounds like the Windom prefers the higher octane juice.

[Steve]

for the first time today i booted the car real hard and it shifted and sounded real sweet....

certainly made a slight difference.

[NotoriousREV]

I reckon you'll get more miles from a tankful, unless you keep booting it :D

[Steve]

i wish i had set the ODO now to Zero .. would like to see if i save some lolly on fuel
