Supermarket fuel

Strider590

Just to point out it's not about extra additives, as some poster mention......

It's about the quality of said additives.

All of my cars have been run on supermarket fuel without any ill effects.

How do you know if you never ran one only on V-Power?

What part of "without any ill effects" didn't you understand?
I have intention at all of trying any expensive fuel when I know it won't make any difference.

Where is your proof that Morrisons, Tescos and the other supermarkets don't put the same additives into their fuels? Are you assuming that a higher price automatically means better additives?

Supermarkets are not always cheaper - often big brands match or undercut them. Currently my local Tesco is at 130.9 for unleaded with both Texaco and Shell nearby at 129.9.

The Major oil companies do not supply additive to other oil companies or third parties. When fuel is loaded at distribution terminals each of the Majors have their own dedicated automated additive injection systems which ensures that each Major only receives its own additive. At the Stanlow distribution terminal, for example, every driver is issued with his own swipe card which allows him to load the correct additives, third parties cards are not programmed for additives, most,if not all, distribution terminals have a similar automated loading system.

Depends what car you have. Mine will only take RON98+ else you risk blowing the engine. It's a pain because the closest V Power garage to me is 18 miles and another 22 to the next.

I've driven plenty and run plenty of motors. Some ran better on branded fuels. Most ran fine on supermarket fuels. It's very subjective. You say No, others say Yes, I say maybe.

Must admit that the VW 1.9TD engine in my Octavia returns the same MPG regardless of whether I am using supermarket or branded diesel.

That is my experience with exactly the same engine as you (and a 130K mile 1.8 petrol Ford engine). I recently undertook a 3000 mile trip to Europe, using only the finest, cheap as possible supermarket fuel, and the car maintained 56MPG throughout.

What are you driving?

If it's something with a modern injection system I'm not convinced.

Probably an Impreza/Evo/Jap import.

RS 182 Cup. It would run lumpily on 95 RON but it would damage the engine with extended use, hence the warning on the filler cap. Subarus are far worse, though, and a single tank of 95 can blow the engine as happened on both my mechanic's car and my neighbour's, both UK models.

What does the handbook say?

The sticker on my Saab recommends 98ron but the handbook says it will run safely on 95ron but with some power loss.

Surely your Clio has knock sensors & adaptive ignition timing?
