Never tried it but always treat my Alfas to 97 Ron, (or higher) as they seem to run more smoothly.

 

ECU is only mapped to 95 RON, but I always Shell V-Power for the additives, keeping the injectors clean.

+1 for Redex, goes in mine straight after winter lay up.

 

Worth doing, it's only going to do good.

 

Amazing off to Halfords now to by some Redex !!

 

yes used it does seem more responsive and runs better, i am sure i feel real benefit not just imagining it................ £5.49 i think mine was cant be bad even to try it for that tiny amount

 

In days of old it was always assumed to be a good way of de-gumming piston rings and valve heads?

 

Just been looking at BG 44K as an alternative.

Anyone tried it?

 

Much better, IMO.

 

Give her decent juice and deposits fly out the pipe? :lol:

 

I had an MOT failure for emissions on an old MR2 I used to own. The mechanic recommended Redex and going for a *legal* fast speed blast down the motorway. It did the trick!

I would only do it every six months though, to get the biggest benefit for your money - you have to build up the crud before you can shift it. Unless you regularly use fuel with additives after Redexing it.

 

Good fuel, fresh oil and a new filter on a regular basis works fine I reckon without much else?

 

Cataclean

Costs abit more but the results are better

 

These 2 work well £10 from Halfords, i get 70mph easy in 2nd now. Even with normal 95Ron shell.

Tryed cataclean but i still get that eggy smell maxing 2nd & 3rd

 

Erm how does that happen?
Redex doesn't alter the gearing

 

Using Redex in my Volvo put my emissions light on, that's all I'm going to say!

 

I just use BP Ultimate in my GTV, it give you a better mpg and has the benefit of gently cleaning the engine too.

 

This is the stuff to try, cleans out everything

Injection Correction.

Also use Tesco Momentum fuel I think it's the same as Shell V Power but a bit cheaper and, if you shop at Tescos, you can get points to reduce price further.

 

The gear ratio and rev limit will determine your max speed in second. A good performing engine will get to that point quicker.��

 

Redex is a detergent, when added to the fuel it cleans anything that the fuel comes into contact with. It also prevents deposits building up. Use it regularly and you'll get more power and better fuel economy. Per litre of fuel, it's cheaper than 97 Ron, which has no benefit for GTV's

 

97Ron in my view should be only used for the track and high performance driving only, that's what it was designed for.

By using it & being stuck in traffic is going to just carbonize your sparkplugs, as the higher octane fuel burns slower.
So by trying to clean your engine by using 97ron can make things worse because of the fuel isn't burning properly at low speeds.

Imo only use the 97Ron fuel if your going to run the engine at high speed, ie once a month on a country rd blassed or on a track.

 

the only time i use 95 is when im stuck away from tescos or shell. its a sports car.its been tuned for performance. high octane fuel burns cleaner ,hotter and releases more power. in the long run you also get increased mileage which offsets the extra cost,better running engine and lower service costs. as a garage owner i advise all my customers to put the best fuel and oil in their cars and without exception when they do they report a much better working car as a result. cheap fuel and oil will bite you big time in the long run. why buy a sportscar and treat it like a punto.
