I would use 95 octain or 98 but don’t touch e – 10 but check with your mechanic first but they mite adjust the timing for 95 or higher. I know someone that had volvo 740 converted lp gas and he had to get the timing adjusted for lp gas but it would ping on petrol but it is amazing how many people put regular unleaded into europeien cars and the lowest octain is 95 because they don’t have 91 octain in europe and there are japanese cars in europe and you would be better off using 95 octain and even japan as higher octain unleaded then 91 octain and i had a 1997 manual toyota prado and i only used 95 octain unleaded and i did 148,000 km in it and i had it since new and if i used 91 octain it was slugished and i used shell semi synthetic engine oil 15w40 in it and the compression was perficed until i traded it in for another 4wd

Hi Marg

Use whatever is recommended in the owner’s manual – the vehicle will not benefit from using a higher octane fuel than recommended. Exhaust systems rusting out was only an issue with leaded petrol, which had acidic scavengers in it, so you wouldn’t expect any benefit in exhaust life from using premium rather than standard petrol.

Cheers

I have always used unleaded in my 1994 Honda Civic until recently. My grandson has filled it up with Premium Unleaded. He says it will run better and I will not need to replace my exhaust every two years as happens now. The car is not used often and mainly for short trips around the local area. Should I continue to use PU..

Hi,
I’m running a 2004 VZ Berlina I used to use unleaded which I was getting pretty good consumption out of. But then I started to just use 98 it made an improvement in fuel. Then after a month or so after all the crap was cleaned out of the engine I noticed a big difference in better fuel consumption and power.

Putting fuel of a higher octane than recommended is a waste of money, as the vehicle will not run any better. Refer to the owner’s manual for the fuel octane recommendation.

Any vehicle that used to use leaded Petrol should be using a valve seat protection additive. A 1966 Falcon should run on 95 or 98 octane fuel if the vehicle has not been modified.

what if you use higher octane than your required octane requirement of your car is it good?
its all base in comp ratio if its too high octane nothing beneficial will give to you
and it cost more than you ever think

My partner just put Mobil’s 98 unleaded in his 1966 Ford Falcon and it has been running horribly. I just read that he may require an anti-valve seat recession additive. Ah I knew he should have just gone to Shell and got 95…
