DerekS Posted September 9, 2017 Report Share Posted September 9, 2017 There's an interesting article in this month's Classics Monthly magazine about fuel additives. What I didn't realise was that fuel companies vary the blend 4 times a year, so apart from any other reasons, a car with summer fuel in may be harder to start in winter...

JohnD Posted September 9, 2017 Report Share Posted September 9, 2017 Any experience with storage/overwinter additives? I've used Briggs & Stratton "FuelFit" with success. It's designed by lawnmower makers, whihc should know what they're doing! John Link to comment Share on other sites More sharing options...
Colin Lindsay Posted September 9, 2017 Report Share Posted September 9, 2017 When I laid the GT6 up two or three years ago through lack of free time to get an MOT I drained the fuel tank completely due to all the scare stories of ethanol eating through everything whilst idle. Most winter layups in the past, the tank was run down to the bare mininum thereby requiring fresh fuel when the next season started. (I was always pinching quantities for petrol-driven tools anyway so it got lower, and lower... ) Anyway point is that if laying the car up for the Winter I'd run it right down beforehand rather than leave fuel to go stale. Or go bang, which was always a risk in my garage.... Does it do more harm: leaving components dry and fuel free, or full of fuel whilst idle for long periods?

AidanT Posted September 9, 2017 Report Share Posted September 9, 2017 I lay up my GT6 over the winter but run the engine regularly Even fitted an exhaust extension to the outside as the garage is double length so saves messing about with both cars Anyway. I've never had a problem with stale fuel so I would be very interested if there really is an issue here Aidan Link to comment Share on other sites More sharing options...
JohnD Posted September 9, 2017 Report Share Posted September 9, 2017 One of my engines was built right on the edge of too high compression. On the fuel that had sat in the tank while it was built, it pinked, badly. A tankful of fresh stopped it. JOhn Link to comment Share on other sites More sharing options...
Qu1ckn1ck Posted September 9, 2017 Report Share Posted September 9, 2017 I have never noticed a problem with stale fuel in stored vehicles. I tend to keep petrol tanks full to avoid them rusting quickly when empty. Link to comment Share on other sites More sharing options...

dougbgt6 Posted September 10, 2017 Report Share Posted September 10, 2017 My car sat in the garage for 20 years with the same tank of fuel. For the first 15 years it started, eventually, every time I occasionally tried it. Now I put the car away in October with whatever's in the tank and get it out in March with no obvious detriment to performance. I took the everyday for it's MOT and the MOT man was telling me a tale about fuel going off within a matter of months. Is it true? I'm not sure I believe it. Fuel additive turned my plugs pink and I couldn't judge whether I was running rich or weak. It didn't seem to have any other effect. so I gave up on it.
