You didn't do enough digging Octane number applies to petrol not diesel and is irrelevant. You need to look for Cetane number as thats applicable to diesel.I've done some digging on this and high octane gasoline is only regular gasoline with an additive to give it the extra 2 octanes,
however there are rules coming into force for 99 octane gasoline which will be its own stand alone product made to 99 octanes.
Hi -You didn't do enough digging Octane number applies to petrol not diesel and is irrelevant. You need to look for Cetane number as thats applicable to diesel.
However even that isn't the whole story as the Cetane of Shell regular fuel is 53-55, whereas for the premium version it is lower, 51-53.
Did you use the service pack first or just straight on to the fuel additive?Sorry not to get back sooner….Simply answer don’t trust reviews but do believe if half of the claims are good …then give it a try …if no different only wasted a few Quid … but it seems to work
OK, I get that, but it doesn't explain why Shell premium diesel (ie V Power has a lower cetane rating than the normal stuff.)Hi -
I was referring to petrol as the post I was replying to mentioned petrol, My original comment on this thread was how shell V power diesel is simply an additive added to regular diesel, which only costs pennies to add, then I replied again after asking at work to confirm that it is the same scenario with gasoline, which is made to a standard then 'topped up' with an additive to become premium gasoline.
However the government is changing the standard of petrol this year and for some reason this means we'll start making 99octane gasoline which won't be an additive added to a base gasoline, it will be its own standalone product.
Went on fuel additive ….as mine is a low mileage 204 ( 18 plate )Did you use the service pack first or just straight on to the fuel additive?
Ok, thanks. 2016, 50k. This isn’t something I’d given any thought to but if it works, it works. I‘ll give it a go, service pack first.Went on fuel additive ….as mine is a low mileage 204 ( 18 plate )
Or you could go to Costco. Buy Premium fuel with the additives for a lot less than V Power.The way I look at it is those brand additives cost peanuts to add to the fuel, if they made a difference supermarkets would add them and charge the same as Shell and BP.
Chanel or Lynx? It all does the same job.
Not the information I have.Some more inside information ,Costco is esso fuel they obviously do not have there own additive and buy esso’s fuel.
Not the information I have.
Well all fuel cones from the same pipe. All the lorries line up.what have you been told ?
the fuel at Costco Gateshead is 100% essos
this is some
It is a free choice for everyone and there will be lots of people that have used supermarket fuel with no issues and those that perceive a benefit in spending a couple of extra pence per ltr more, I'll stick with my decision on this.I’ve got a 20 year old A4 TDI parked outside with more nearly 210K miles on the clock, it’s never had anything but cheap supermarket fuel, I had the EGR valve out for a clean at about 160K, it had normal carbon deposits.
20p / L over 20 years is a lot of ££££££
