Petrol Additives
 

Does anyone have an opinion on Petrol Additives?

Re: Petrol Additives
 

What addatives ?

Re: Petrol Additives
 

I've always used Redex to keep the carburettor jets, then the injectors clean.

But E10 has raised a requirement for some petrol cars to need a "dispersal agent" to break up the water that forms in the tank due to the ethanol, especially if you are a low mileage driver, or drive with an almost empty tank. My friends in Canada recommended a few, but they are not available in the UK. This also applies to lawnmowers and chainsaws that are stored with fuel in the tank for long periods.

Terms to google: Sta-Bil, STP ethanol, phase separation.

Re: Petrol Additives
 

Google "lawnmower fuel stabiliser" and you'll find a few for silly money. Personally i stick to E5

Re: Petrol Additives
 

They claim to improve fuel consumption, keep injecter clean

Re: Petrol Additives
 

I would have thought that the only time additives would be needed was if you're running a classic vehicle that was designed for high octane (>100) leaded petrol especially if the engine wasn't modified for lead free fuel. Even then an octane booster like methanol would still be needed as the fuels today are really low grade.

Re: Petrol Additives
 

Yes, but which addatives are you referring to or are you referring to all addatives no matter what they purport to do?

Re: Petrol Additives
 

Many stores sell them under different names, the most common name is Redex

Re: Petrol Additives
 

I used Redex many moons ago, but in the last 10 years I use BP Ultimate fuel depending on the engine type.


Currently its diesel and I paid £2.11 a litre at the height of the great fuel rip off.

Re: Petrol Additives
 

I have never used one, and never really seen what use they are.

E10 is a non issue to me as my car is diesel (as all my cars have been since 2001).

Re: Petrol Additives
 

I don't have time to um and ah about refueling my car. It takes unleaded and that's all I need to worry about apart from price:rolleyes:

Re: Petrol Additives
 

My car loves E5/99 octane due to the car it is and its tuning, so also don't have to worry about the ethanol problem.

I think Reddex is the only ever thing I have put in a car as an additive. Have read some advertising stuff about some giving you more miles per gallon but no idea how true that is or if there are any negatives to using them.

Re: Petrol Additives
 

As long as your car is E10 fuel compatible you should be ok just filling up, if not then E10 is said to damage the engine.

Re: Petrol Additives
 

My car according to the handbook can run on 05 or 10 but it runs smoother on 05 but my local garages which are BP or Shell often only have 10.

Re: Petrol Additives
 

In the first episode of 'Porridge', Fletcher adds his own additive to the prison van. Worked for him :)

Re: Petrol Additives
 

Redex was the additive to use back in the 60's, I haven't used it since 2000 when I got a new Zafira!

Re: Petrol Additives
 

I used to religiously fill up at the shell garage but with the increased prices they really took the piss at my local garage costing so much more than everywhere else. So I started to drive to bit further to Tesco during that and never gone back to Shell since.

One would assume that the Shell 99 octane had better additives than Tesco's (if they have any) but the drive is exactly the same.

Because its a performance car I can definitely tell the difference between using E5 vs E10 though. Its why I stuck with it from the start.

Re: Petrol Additives
 

I have no choice but to use E5 in my car, unless I want to end up in the garage sooner than expected! I use either Tesco or Shell. Both do a good job. Never been impressed with the BP ultimate fuel. The car never feels as punchy as it does with Shell.

Re: Petrol Additives
 

Shell E5 fuel used in my 05 Meriva plus expensive petrol mower used by our group cutting grass in the local church yard.
Without the Ethanol mix of E10 much better responce/less contamination of fuel lines.

Re: Petrol Additives
 

When E10 started appearing on forecourts I switched to using Super Unleaded (E5) in my petrol mower, not because of performance issues but because there’s a long off-season in Scotland when E10 left sitting in the mower or in the jerrycan might degrade and cause me problems next year.

But jings and crivvens, my old mower revved like something out of F1 the first time I put Super in it :rofl:

Re: Petrol Additives
 

I'd say most modern engines would not need additives, especially not on E5, as the fuel likely already does the job. If you get your car properly serviced the garage could tell if you need something extra while they change filters/plugs etc.

If you had added "help ma boab", you would have had the Oor Wullie trifecta… :D

Re: Petrol Additives
 

Zx1 Extralube. Whenever I get a new car I always buy some for the oil tank, fuel pump and gearbox as well.

It’s never let me down in 20 years v
