Redex petrol additive

[benny3008]

Anyone used it? any good? Also, should I follow the same directions used for a car for use in a 50cc engine?

should nt use it in a car - certainly not for the major brands. At the loading gantry they put additives in which help meet their own quality standards. I have always gone for Shell or Chevron as these are richer in detergenets which help keep the engine cleaner and actually do have a beneficial effect to economy. In the US Shell are now advertising the gains - they havent been brave enough over here yet, but they have fuel comparison tests for various vehicles and gasoline (petrol). Redex can also throw the balance of lubricant additives as well.......

Yes I do Benny.

I have a 1984 VW Golf and I've used Redex for a few years. I always fill the tank completely at the pump and I put one measure in the tank every three tanks. The reason I don't do it every tank is that the Redex will gradually concentrate and you'll have too much. It's cheaper to do that too.

My car has a single carburetter but I really notice the difference every time I use Redex. The car is noticeably sharper and perkier and it certainly runs beautifully on a long distance trip. The smaller bottles are quite expensive but I've found the cheapest way to buy Redex is by purchasing the 1 litre bottles from Halfords. Then decant the measure into a small 250ml bottle to put in the tank.

It certainly helps my old Triumph spitfire run smoother but I see no advantage in using it in a modern car.

Use it as directed but if your 50cc is a mower or two stroke - dont.

[DTCwordfan]

on very old vehicles it can be used for valve clearing but it can also strip the seals on the pistons and then watch your lubricant consumption...............

[mjwman]

"strip the seals on the pistons" where do people get their ideas from?
That is a meaningless comment.
And total b******s

I would like to apologise for my last comment made late at night after a couple of malts!
After posting I realise now that DTcrosswordfan was not actually talking b******s. I now see he/she meant by "seals" the ridge of carbon that builds up on top of the pistin. When decokingh an older engine you should leave the carbon round the edge of the pistton to help seal it.

With modern engines on modern oil I do not think you will get the buildup we had in the 50s and 60s. so the comment can still be ignored.

No matter, I was rude and I apologoise.
