E10 Petrol for 2007 Quattroporte

[robert-jones]

Good Morning,

GOV.UK website dosen’t cover Maserati any idea if E10 petrol is safe or still use E5?

I’m sure it’s not for the 3200. You’d have to check the handbook for the later cars.

The safest bet is to use ethanol free petrol in pre-2011 cars and unless I am mistaken here in parts of the UK that is only supplied by Esso. It has an octane rating of 99 and the pumps have a label E5 but that means up to 5% and if you consult Esso’s website they say it is ethanol free. The problem of course is that it is expensive but depending on the miles you do is cheaper than having to replace damaged fuel lines, catalytic converter etc.

I emailed Maserati Customer Services some weeks back asking for guidance for both older and newer models .  The reply was pretty ….. trying to think of the right word. Basically it was “consult the handbook for your car “ and “ask your dealer”. I replied back and noted they didn’t really answer the question and also said nothing about older models . The reply to the second email was also pretty “lacking”.

The best place to look for guidance  at the moment is the FBHVC Press Releases that have come out over the last weeks with the latest on 2/9/21 .

Chris, I agree with you about the use of Esso Supreme 99+ as an insurance against ethanol damaging some of the older cars. I am not sure about the use of fuels in a QP V and as you have discovered the manufacturers and dealers do not want to make any statements that may give rise to later claims for damage. It may cost more but most of the older cars have a low annual mileage and so the cost is bearable at present. I still use TetraBOOST in my Indy (1972) and am considering adding it to the fuel in my 1990 Biturbo 222E where it is supposed to counteract for up to 15% ethanol. Neither of which has a catalytic converter. The lead content in TetraBoost would kill a catalyst in the QP V.

Cheers – Keith
