Thread: which fuel to run

I run my V6 FL1 on Premium. I wouldn't put that Ethanol crap in any car of mine!! Seriously though, Premium is the standard fuel in Europe and all European cars are tuned to run on Premium!! The manual in my car only recommends running on lower fuel ratings for short periods of time in an emergency!! However, I am not sure here, but do some research on the internet as I think the FL1 can be retuned to run on standard!! Anyrate have a look at this:

thanks no youve answered my question nicely.. n ot sure about us down south having ethanol in our fuel , its just lower octane far as I know... regardless. I did 'accidentally" put a 1/4 tank of stock unleaded in it once and it ran roughly till I topped it right up with premium... looks like im stuck with high fuel costs.. thanks for your help

I appreciate that Ausfree always answers questions as best he can but in this case he has not answered the question - he has given information for the V6 (which I am sure is totally correct) but we are talking about a 1.8 not the V6.

My handbook has minimum octane for the 1.8 of 92 which is standard unleaded.

bugger.. i didnt notice thet the answer reffered to the V6..

in that case can someone answer me who actually RUNS standard unleaded in their 1.8 FL1?

I cannot afford to screw up my engine cos I dont have the funds to take it to a rover mechanic.

sorry to be a nuisance.

You are not being a nuisance mate, and I will stand by what I said. As far as I am aware standard unleaded has 10% ethanol which can do damage to a vehicle not designed to use it even though it will run on standard without Ethanol!! Be careful and seek advice from experienced mechanics on this. As far as I am concerned, use Premium and there is no doubt!!

I agree with Ausfree - I wouldn't be using anything with Ethanol in it before doing my own research - noting that Premium could also have Ethanol in it.

Supposedly it is all Ok but I am not so sure - works well in engines designed to run on ethanol like GM Aust Engines sold in GM products in South America but the engine needs to be designed to run on it from scratch.

Don't mean to be argumentative (just want to get to the bottom of this)my hand book from my 2001 model FL1 says the recommended fuel for the 1.8 petrol engine is a recommended 95 Ron and that engine has a 10.5 to 1 compression ratio. It also recommends a 95 Ron fuel for my V6 which also has a 10.5 to 1 compression ratio. Has things changed between the year your vehicle was manufactured and 2001????

Not at all - certainly the 98/99 handbook has it listed as 92 Ron and goes to indicate that higher grades can be used without detriment but lower than 92 RON can only be used in emergencies and for short periods only.

If your later handbook says that it is 95 Ron it is obviously the case so maybe there were changes around the time the engine was dropped.

Maybe Bigfitzy needs to follow the information contained in his handbook - however if he is in doubt then he should use 96 - every one agrees there are no issues with that grade of fuel.
