Gull have just opened up right outside home and are selling Gull Force 10 (E10). does anyone on here use it in their stock NA's and if so how does it run?

Looks like that could be a no?

Yes I did read in the list of cars that NA and NB's are a no go. Might just stick to the 98

I used it in my car for a while. no issues. changed to mobil 98 now

Gull 98 good. Any other 98 makes it run like arse.
Mobil 95 is the best so far. 10 degree or 14 degree timing.

IMO running the E10 ethanol blend in a stock NA is a waste of money that could lead to fuel system issues.

The car was designed to run regular unleaded fuel (~90 RON in Japan), most of them should be fine with 91 RON, even with slight timing advance (running 95 in this case would give a safety margin though)

Any performance gains from running 98 in a car tuned for 91 are an example of the placebo effect, and effective marketing from petrol companies.

Whahoo, but my bastard child of a car can run it.

Might have to see whether the place in Greville Road has it, get the business to get a fuel card from them if they do, especially since there is a Gull next to Hampton's now.

Can I run that???

Not with your current fuel setup Donovan. E85 is corrosive, you would need to change to a pump and filter system to suit it along with a tune and potentially a flexifuel sensor as NZs E85 has been known to be inconsistent.

In short its best to stick with 95/98 octane unless you're really in need of it.

Just my opinion, please correct me if I am wrong.

No corrections; just an additional note - No idea how the consumer available E85 is handled (pumps etc). But TRS has to order theirs in for each meeting and unless the next meeting is within ~2 weeks, they will normally just ditch it since the aromatics that make up a large concentration of ethanol based fuels tend to disappear (evaporate etc etc). Hence the flexifuel sensor requirement to try and account for this as best as the ECU can. They run near-grenade tunes on those engines though so that's probably why they ditch their E85 barrels after a certain time. A tune for a road car will need to be a bit more conservative to account for E85 not quite being E85 after a while.

being hydrophilic, it'll also become more watery (technical term

over time ... for non-racing uses you have worse mileage to deal with as well as the corrosiveness.

I'd stay far away from it personally!

and its pretty much useless if your running NA, unless it tuned VERY hard

Erm, if we're being pedantic, I think the term is Hygroscopic
