edwardio Posted April 7, 2011 Report Share Posted April 7, 2011 Interesting reading, though a little flawed. Not every fuel supplier was tested & only 1 car in each class. I did tests in my 140, comparing Shell Unleaded, V-Power & a mix of Acetone in both. It turned out V-power produced a 10% increase over standard fuel. An acetone mix was better in both fuels, but V-Power was the best cost effective option. Super fuels do not need to be as much as they are though.

Angus Posted April 7, 2011 Author Report Share Posted April 7, 2011 Here's the graph thing from their piece: Yes, your test made for good reading, and encouraged me to go out and buy some acetone which seemed to inmprove things for me. However, when I ran out I never got round to getting more. Angus Link to comment Share on other sites More sharing options...
rpsmith79 Posted April 7, 2011 Report Share Posted April 7, 2011 As i have said time and time again, using higher RON fuel only makes any sort of difference if your engine is capable of using the extra compression before detonation Higher RON fuels only work on engines that are running a compression ratio of higher than 10.5:1, but the higher the ratio, the better the gains as the engine can wait longer before detonating the mixture Higher RON fuel just means you compress the fuel more before pre-detonation occurs Link to comment Share on other sites More sharing options...
edwardio Posted April 7, 2011 Report Share Posted April 7, 2011 Acetone does the job, but the cost mounts up & the worry of seals etc failing! Their write up was good & done in the road, not like the fuel silliness who probably did it in a lab. Though to fully test it all needs various makes, models, engines & years. It's just like fuel cleaners (redex, stp etc), they do work to different degrees, but not enough to really offset the cost of regular cost.

hyper-wrap Posted April 7, 2011 Report Share Posted April 7, 2011 I only noticed a difference in my MR2 tubby...it idled nicer with higher RON fuel. Other than that, the performance promises seem to be almost total bullshit. Link to comment Share on other sites More sharing options...
pete66 Posted April 7, 2011 Report Share Posted April 7, 2011 Please don't tell me acetone mixed with the juice improves car performance and economy. I once worked for a firm that had barrels of the stuff on tap. Link to comment Share on other sites More sharing options...
mcwillo Posted April 7, 2011 Report Share Posted April 7, 2011 I currently work for a firm who has barrels of the stuff on tap What's the score with it then? Or are you going to make me find out for myself.. If it's genuine and not dodgy I could organise a group buy no problems... Link to comment Share on other sites More sharing options...
edwardio Posted April 7, 2011 Report Share Posted April 7, 2011 Basically mixing PURE acetone with petrol allows it to burn better and therefore, more of it actually ignites during combustion. This gives more performance & better mpg. Plus it helps clean the engine. The down sides are that it eats cheap plastic & rubber. Although Mr.T uses good stuff, you can't be certain. You CANNOT get this on your paintwork as it WILL strip it! Plus you must get the mix right. I think it's 2.5ml per 1ltr of fuel. Over that & it doesn't work, under & you don't see the full benefit. You'd be better off just using a good Super Unleaded. Link to comment Share on other sites More sharing options...
mcwillo Posted April 7, 2011 Report Share Posted April 7, 2011 Just read this monster thread on another forum from a few years back. It's an interesting read and I'm very tempted to give it a go. In the amount we're talking (1 part in 400), ie about 135ml in our tanks, I agree with most on the thread - it's not going to do any serious damage to rubber components since it's so diluted.

edwardio Posted April 7, 2011 Report Share Posted April 7, 2011 (edited) Mixing actone in standard Shell = V-power (pretty much producing the same results as plain V-power tests) Mixing acetone in V-Power = slightly better gains, but nothing worth the money.

Bill T Posted April 7, 2011 Report Share Posted April 7, 2011 Premium fuels are all hype IMHO. It seems to me the older the driver the less likely you are to use them, simply becausewhen you've been taken in for a few years you eventually see through it all. I've been using supermarket swill for more years than is decent and have never had a fuel related problem, despite all the sand, camel shit and old bus tickets I've been pouring into my tank.

edwardio Posted April 7, 2011 Report Share Posted April 7, 2011 I think it was 100ml, as I didn't want to mess around measuring out the other 25/35ml, as you need to do it from a glass measuring cup/jug. If you do it in a plastic one, it'll etch it on contact Link to comment Share on other sites More sharing options...
mcwillo Posted April 7, 2011 Report Share Posted April 7, 2011 I work for a chemical manufacturer so the stuff I have available will be free of impurities... Think I'll start a few tests of my own. I've not yet finished my 2nd tank after adding BG44K yet though - so maybe have to leave it a few tanks to prevent any outside influences affecting the result. I'd love to hit 400 miles out of a tank but most I've ever had was 326. Link to comment Share on other sites More sharing options...
Sherv Posted April 7, 2011 Report Share Posted April 7, 2011 (edited) I remember Retro Ford did this test a while back on tuned Pinto's ,couple of high spec X-flows built by Harris and a YB Cossie lump in a mk2 Escort i think it was amongst others,they concluded that the only real world gains were on the turbo spec car,the rest were more negligable,and a placebo effect on most.Worth pointing out that Jap FI cars like a GT4 are designed for optimum performance with a high RON fuel,standard fuelling ECU or otherwise,typically 102 RON which is why faff owners in the know generally prefer to run their cars on the 99RON we get over here.You could probably argue that a 3sge being of the same place of birth could also be included in that theory; but i think the turbo engines of a more 'specific' design are the real beneficiaries.Like Bill says most of the N/A cars are generally run on tramp's piss,and dont seem to suffer unduly.Other than the smell of piss,obviously.

NJay Posted April 7, 2011 Report Share Posted April 7, 2011 I can not run on anything less as the car was tuned with shell vpower running through its veins,for several tanks. Boo LOL. Link to comment Share on other sites More sharing options...
NJay Posted April 7, 2011 Report Share Posted April 7, 2011 It's one of those undefined mysteries of the gen7 sportsm in that sod all appears to have been done to the engine and it produced 200ps vs 190ps. Was that down to the trd exhaust and ecu remap to narrow the margins on the type or fuel used. Afterall some of the gains I have will down to tuning it without causing knock which will be potentially lower on the super unleaded? I suppose if I had the bottle, seeing as my powerfc controller always shows me a live knock reading I could run it on 95ron rather than 99ron vpower and see what it shows but do I want to chance it lol Link to comment Share on other sites More sharing options...
antmax7 Posted April 7, 2011 Report Share Posted April 7, 2011 the whole point of using V-POWER which was not even included in that test is it contains cleaning agents! the extra mpg is mainly a result of this as it is a much purer fuel. i will use nothing else only bp ultimate if i am really really desperate but may car even states on the fuel cap 97-98ron fuel MUST be used Link to comment Share on other sites More sharing options...
