15% ethanol in fuel
15% ethanol in fuel
(OP)
I have a car with GM 3800 supercharged v6, 5 fuel injectors failed all at the same time. They would leak all the fuel line pressure into the cylinders/manifold making the car extremely hard to start.
The guy that fixed said he has been working on GM cars for 25 years and never seen five injectors fail at the same time in the same way ....he said the seats/seals in the injectors were eaten up
I am wondering if this could have been caused by the ethanol that is in all fuel these days (15% at stations near me)

Next time you inadvertently get a 'tank of regular', just take it easy on the throttle to a half tank or so and then fill-er up with 93.
We get a choice of 91 or 87 and I have a car that "requires" premium and I have operated it on "regular" for nine years/170,000 miles with no problems...in fact it has only had one set of plugs and one COP replaced in that time!
I do not use any of the 'snake oil' products, either. Waste of money...Same deal for the HUGE octane improvement of 'premium'.

It is a striking coincidence, but at the same time, the injectors are all equally old.
Could it be possible that one injector got to be bad enough to leak down at standard pressure, and as system pressure dropped, other injectors that could otherwise stay sealed would leak down?

Although we had the fuel rail raised and when you turn the key on to build pressure then turn it off they all seem to start leaking at the same time so its hard to say.
I bought an entire new set and replaced them all just in case.
