Did ESSO kill my car?
Couple of weeks ago my engine went pop (again!). Its a fully forged engine with 550's, Headers, VF-34 etc etc. Basically a pretty safe motor?!?!? ......One would think!
Anyhoo after inspection I was told that it seems it was under fuelled. Possibly MAF failure?
So I am now having an after market ECU (to rid me of MAF) and also a paralell fuel rail for safety and Knock and Lambda Link to go with my Mass of Defi Gauges.
Damage this time seems to be a couple of pistons starting to melt and a melted exhaust valve.
Quite a worrying thing happened though. As I popped in to see my car last saturday morning and drop of some stuff. Results came back from my fuel in the Tank.
Now I always fill up at my local Esso station. Its quite a big one on a very busy road so you would think it would be used regulary. I ALWAYS use 97 and ALWAYS an entire can of Pro Boost purely for safety.
The result that came back made my heart sink. The fuel in my tank was a sickening 97.2!!!
Not only do I look like a complete.....ahem as it seems as if I have not fuelled my car correctly but maybe it contributed to my motor going bang?
Who knows but im starting to get a bit fed up of it all. I may actually go to that station and buy some 97 and 95 and have it tested.
Just though you should know as I've had a pretty rubbish experience and I would not wish it on anyone!
Cheers

well so the argument goes that optimax is not refined at 98RON but merely 95RON boosted , which is why i know of people who have tested it after a long time.
which would also tie in with esso sul being 97.2 after a few weeks as the booster would of dropped off and returning to its REFINED state for which esso is refined at 97

The problem with SUL pumps is they are used nowhere near as much as NUL pumps. Petrol does indeed go off
...any avid 2 stroker will tell you after a lay up over winter - next time you come to use it, the engine is down on power and is a pig to start (even my leaf blower!) - even when using pre-mixed fuel kept in a sealed jerry tank...drain and add fresh fuel and its back to normal. I guess the same applies to petrol station tanks too.
Then there is issue of overall quality, I have had the unpleasent experience of a tank of optimax petrol containing too much water - well, enough to randomly cause the engine to cut out and causing surging at held revs. Something I have never seen or heard of before, but if it happened once it can happen again. (although excessive water in petrol may be handy if your running lean...water injection
)
There is a fair deal of info on a few american sites about petrol quality which I did once find via google...but I don't have any links handy though - sorry. But with a few choice keywords I'm sure you can find it yourself
All I can say is always map the ECU conservatively - especially with JDM imports or with mods.

i agree with the ****e batches of fuel you get with optimax. i normally get 2 ****e batches a month. it really annoys me . your cars running great then after half an hour of your fuel fill your cars running ****e.infact i can remember my first scoob would suffer badly.i took it down to merve at power engineering to find out what was wrong with it.he advised me it was bad fuel .to be honest i thought he was talking out his ****. but he was right i waited until the car was empty used another garage and the car was fine.£95 for the tune was what really annoyed me.

i agree with above.i have an expensive 2 stroke strimmer and the manufacturer advises that after non use for only a few weeks even,the old fuel should be drained and a fresh mix added.i fuel up 3 times a week at the same petrol station from the same pump if possible.at least i know that its being used regularly.

I think its Number 2 piston that is common as apparently it is last on the fuel rail. Hence me getting a different fuel rail.
I still think the fuel could be poo

well i just started to think it was a con this booster lark anyways - i mean how does a 1/3 of a bottle up 50 l by 2/3%...
I guess i was lucky with my sti -didnt modfy beyond bigger downpipe ( even this was a worry)..........just goe to prove the only sure way is to remap for english regular fuel.
oh,... an ive started a 2 stoke outboard on mixed 5 month old fuel with no problems....

btw when you say superchipped do u mean bleed valve as you cannot superchip a r5 in the strictist sense, superchip kits for the 5 consisted of a bleed valve and rejet if your lucky!

Luke C, I'm surprised that you modified your engine but didn't add a knocklink or Lambda link as a minimum. A forged bottom end won't save you if your fuel is bad or lean obviously. It may well have been your MAF. Who mapped the car, are you using an induction kit and what other mods did you have?

Hi Floyd,
Im not running an induction kit just a green panel filter. In hindsight yes I should have used a Knocklink and Lambda link really.
It may have been the MAF which is why im having an aftermarket ECU too.
Anything else you recon from a safety point of view I could add?
