Shell fuel save petrol any thoughts.
Hi all I have begun using shell fuel save petrol as I have found that super market petrol has been giving me lots off starting problems and another reason.
I have been reading on many forums about it and also the Internet about the pros and cons off the fuel. Personally I have always believed that they was no difference between posh petrols and super market fuel but I must admit I have been converted.
Anyone got any thoughts on it experiences with posh petrol's [/i]

When they first advertised Optimax,they showed a head removed and how clean it was after x amount of miles.
At the time,my daily had a hg failure,I put a recon head on it,then only run it on Optimax.After 10k I had failure again,! My head was filthy,nothing like what was advertised.
I don't use it anymore,good old supermarket petrol for me

I used to always use the super market petrol but it started giving me a problem after a while some off it was mechanical but the fuel is doing what it advertises with mine the injectors are getting cleaned out. The engine is running much much better so far this is my second tank off it and the engine does seem to run a lot smoother and more powerful then before.
Same as you Dave I was very sceptical off the benifits off the cleaning ability off a petrol to clean up the valves and the inlet side off things due to injection off the fuel into the cylinder with out the fuel ever touching the inlet side off things. I defiantly won't be going back to super market petrol and if I do it wil be the super unleaded and a bottle of fuel treatment if I do use it again.

I watched a old 5th gear only they used a golf gti that was quite new on a rolling road rigged up to cans off various fuels. The only one that proved extra Bhp was the shell v power of something like 1 Bhp extra.
But I was wondering I'f some one had used it in a car that had already been run a few years on the road and did they notice a difference in the running off there car on it cleaner smoother.
My v8 discovery seems to like the fuel save petrol quite a bit seems to be less coughing and spluttering like it used to do on the super market petrol as for mpg well with a v8 that is going to be hardly noticeable lol but it does seem to last longer on the fuel save petrol and does take a couple off tanks to make a difference though.

I always stop at the same garage to fill with V Power for racing. Mainly because i like to think that I'm getting the same fuel each time. My only complaint to that garage about 3 times in the last 3 years is the amount of grit I see in the tank and glass filter after about 10 gallons has gone through.
The cashiers say they will tell the manager but I never hear anything back.
I now filter the fuel twice before it gets to the pumps.

My BMW car has a pretty accurate average MPG OBC. When I first got it I brimmed it over several tanks noting the mileage and fuel added and worked out the MPG. Which was within a gnat's whisker of what the OBC said.
At the time, I was travelling from London to the north of Scotland pretty regularly, which used near enough a full tank of fuel. I experimented with different makes and octane ratings. And got no results which were conclusive.

Was the V Power test towards the end of the tests? Did they conduct all the tests again in reverse order? If it were a near new engine, it could well loosen up during full power testing.Big woof wrote:I watched a old 5th gear only they used a golf gti that was quite new on a rolling road rigged up to cans off various fuels.

If it's coughing and spluttering, that's nothing to do with the fuel.

I believe most of the reported savings or improvements for such fuels are in large part a placebo effect. Particularly if you are spoending 10p a litre more (or whatever it is) the driver will WANT to see an improvement or feel even more ripped off!!
RIP MGB V8 .... served me well as a learning curve.

Do you think if I put race fuel and nitrous into my rover 75 I would save money on fuel?chodjinn wrote:I believe most of the reported savings or improvements for such fuels are in large part a placebo effect.

If so can you put that into a coherant argument I can put to the wife? Unfortunally she does not believe me about any "cheep modes of transport" anymore since I argued my Laverda would be "a cheap method of commuting to work" then spent a small fortune rebuilding the thing three times.

poppet valves rule!
From what I saw on 5th gear the tested the cheapest to the most expensive petrols that claimed to increase Bhp just the fuel it's self no mods and after every tank they flushed the system thourgh with normal petrol and started the process all over at the end off the runs they announced the winner as v power then proceded to do a track test with the same car. And she said what she was feeling thourgh the car and response things like that.
My question was had some one used just this one fuel and then stripped the engine to check the claims off shell in the real world situation.

We're all the fuels on test the same octane rating?
If you tune your car on 95 and then put in 98,99 or 100 octane your car will show/fell better performance.
But at the same time expect everything above 95 to cost more.

Hello all I have been away for a while. Fitted a center replacement pipe due to the middle box being blocked up with broken cat material I am looking to tune the engine but its going to be a while due to the cost off the fuel chip for a decent quality replacement chip. Still running fuel save petrol run around three full tanks at the moment.
