Fuel stabilisers

Post by pvr » Tue May 23, 2023 4:03 pm

Just had the Golf MOT done, and as I have only done 200 miles in the last year, the fuel in the car is aging. What recommended fuel stabiliser can I add to keep it ok?

The last topup of fuel last year was 99 octane (as it is a 30 year old car can't use the E10 stuff).

I have an infinitely better suggestion; why not actually drive it, burn off that old fuel in the process, then re-fill it with fresh stuff.

It does 300 miles on a tank, so you can guess how many years :lol:

I've used STA-BIL Storage Fuel Stabilizer in the M140i when it went into storage last September. It's the first time I've used it this time around and went for the 236ml bottle. I topped the tank up and then added the required amount of stabiliser for the amount of fuel in the tank at the time of storage. Will be getting the car out soon so hopefully all will be well. Think I only used it after reading all the stories that the latest fuels aren't good for sitting for long periods.

Take about 10 years to get through my fuel tank :lol:

Most of the problems with the Exx petrols degrading over time is due to the ethanol content - the ethanol is hygroscopic and, in long term storage, it's possible for the water content to reach the point where it separates from the fuel. The water will then sit at the bottom of the fuel tank, which is where the fuel pickup is, and engines don't burn a water/air mixture very well (fortunes to be made if you can find a way to make them :D )

You're filling your Golf with 99 Octane which has 0% ethanol so won't have this problem. If you keep the tank full, to minimise the amount of air in the tank, you should find that stabilisers are unnecessary.

Thanks Perry, will leave it then. It was on the “advisory” list from the service yesterday hence made me think.

Also a new battery, not sure why though and certainly not at £160

Now you have retired and have a lot more free time, that mileage may increase massively......to, say, 100 miles a year! :lol:

Maybe find an MOT station a bit further away; take a picnic! :lol:
