New Tesco Momentum 99 fuel

Filled Flossie with this yesterday and for the first time in the six years I have owned her she didn't pink!!!

Anyone else tried it?

if you were getting pinking then i would suggest getting the timing/mixtures checked..

Timing had been checked and rechecked.  Quite simply, it states in the car that it should have minimum 98 RON fuel - yesterday was the first time I have seen any that reached that!  No pinking any more.

Just to say she didn't pink often - only under load in hot weather.

what actually is "pinking" ?

What's the price? If its as good as it suggests, and cheaper than Shell V-Power (120.9p/litre at my local) that would be great!

I paid 127.9 but I do live in Andover

Is it a formel E then?

I thought they were the only mk1's specifying what was 5 star?

Unless you've got a mk2 16v engine and if you run those on 95ron they blow the headgasket between the cylinders. Had to do my old one twice lmao

The quick fix is just to retard the timing a degree or two, it's a better idea than risking any pinking or knocking.

vpower is 99 RON

Do you get more miles per gallon then on monumentuis?

very interesting - and not necessarily related to spark timing…

pinking is an issue that can occur with any engine, basically it happens when the fuel that is injected into the cylinder explodes before the spark is given and/or the piston reaches TDC.

it is a serious issue because it tries to force the piston back own whilst it is still trying to get up the bore, it also can damage the piston and its rings.

98 was four star. 100 octane was five star.

i wouldn't andover £5.80 a gallon.

C formel E and GTI models specified 4 star in their day. No VW ever needed 5 star. All VW engines from around the 1970s can take unleaded. So with today's fuels, you can run the C formel E and GTI on super unleaded. You can run it on normal unleaded if you take it easy, too.

I took my GTi to Knebworth today & stopped at an Esso petrol station in Woolmer Green(Herts) & they had 4 star leaded petrol,
I thought I would treat the golf to some leaded fuel, couldn't see the price anywhere, so I picked up the pump,
then put it straight back down again:-



 £1.89 a litre :doh:

Was it really leaded, or LRP?

It had the old style red circle with the white 4 stars & said leaded, so I believe it was leaded.

The Ford garage in Marlow,Bucks has 4 star leaded too. Had it for my first tank back on the road. Was pricey though,and it is attended pumps!

Ah yeah, forgot that!!!!

Duh.

lol i'm a cretin, it's official!

But optimax and tesco's stuff does make a difference in the golf. i find esso/total/bp super unleaded makes next to no difference at all.  I gain a few mpg and i can definately feel the difference in torque.  Doesn't make it faster it just seems to cruise happier. idles better too.

I gave the golf  a treat the other day and put £25 of Tesco 99 octain in,well since then i find the car doesn't start so well,normally first thing in the morning car starts on about half a turn of the starter'even when laid up for six months the starting is superb,but now it takes a few cranks then fires but not with the same exhubrance( thats the only way i can explain it) can't wait now for the 99 octain to be used up and revert back to the conventional 95? octain and hopefully the car will revert back to normal.
