E10 petrol

Apologies if this has already been covered. Anyone know the implications for Masers?

Funny how they know our cars exist for tax purposes though!‍♂️

Up to E10 is fine. It’s in the owners manual.

Cheers Zep, I must read that thing one day

It’s a right riveting read, honest

Its fine if you like losing 40 or 50 hp!
I'd stick with E5

Apparently Esso has the lowest levels of ethanol, so I try to get their supreme stuff whenever I can.

US manual says up to 10% is okay also. However, ethanol is hygroscopic and will absorb water from the air. As I live in a very humid area, I only use Shell V-Power N+ premium gas. Don't know if you chaps have the equivalent over there, but it is 93 octane m+r/2 gas only. Works well for me.

I understand your concern, but I would expect that if you keep your petrol in a sealed container I won’t do too much absorbing.

But yes, we have low ethanol here too, but we measure our octane differently so your 93 is our 98 (ish).

Yes, you should always adjust your carburettor for the reduced energy density

What's wrong with 5-star?

Well, unless you just have a natural aversion to pop music.

Swear warning

Where is it in the manual (QP5 2006) - mine only says 95 RON or better.

I should probably clarify, it’s in my owners manual. It might not be in yours, and so you’d have to ask Maserati.

 

[Felonious Crud]

This might be interesting. Well, I though it was.

Blimey, that was a bit tinfoil hat.

I have been reading up on this. It seems, as usual, that there is more than one answer. This will take a while to read:

I does seem to back up the Bamford chaps statement about closed loop and open loop control, in that there is almost no power effect at part throttle and a couple of % at full throttle. In essence, if you can get enough ethanol into the engine, it will make more power, but if there isn’t enough because of the base map, it might be a teeny bit down.

Fuel consumption, which is defined by volume, will reduce as you have to use more to make the same power.

that's an eye opener and thanks for posting, always thought V Power was the best, clearly not, this guy is saying esso ultimate, but does he mean esso supreme+99

That's my assumption. I've a feeling they re-branded it, but could be wrong. Supreme+99 is my tipple of choice, anyway.

think I'll be changing from v power to esso then

Depends where you live. In some parts of the UK Esso Super Unleaded does contain ethanol.
