E10 issues.

siacci · 22nd January 2010, 08:05 AM

I have a friend with a 5 series BMW. He was told E10 was as good as premium as the octane level is higher (or something like it). He filled up and his car ran like ****e. I put some Cleanpower in it to see if it would help and told him to go back to premium. Within in 1/4 tank he said it was running better. 3 tanks (premium) later its a good as gold.

I am dubious on E10.

Well the Pintara had to go to the mechanic to get it running properly. Had a few tuning issues but the fuel in the bottom of the filter was a black colour - seems the E10 has been dissolving the inner lining of the old rubber fuel line. Not a lot but just enough to start blocking the fuel filter - however to be fair the filter had not been changed in a while but there was fine rubber particles in it.

If the car had been in good tune with new rubber fuel line there would probably not been an issue.

they cant provide E-anything or bio-anything without putting some kind of warning sign somewhere.

usually its a piddly little sign buried behind the lollies that you cant read or in very small print on the bowser.

E10 does have a better octane rating than normal unleaded BUT its also got less energy per liter.

its also very effective for dewatering fuel systems and shifting deposits in your fuel lines and filters..

Even if your vehicle is rated to handle E-anything if you've only been running it on normal fuel for quite some time you might pick up some issues while it runs through this process.

Note also the tech bulletin from LR re. ethanol fuels for V8 P38s and I dare say applies to Discos of that era with the 4.0 V8...ethanol attacks the fuel sender which causes the resistance to change which in turn leads to significant deterioration in the fuel gauge calibration: ... the "fix" is a new sender...

Which is part of the fuel pump assembly. OUCH.

just got a quote for a new one for mine for this problem ...$250...
will be changing it over week after next with new lines and dropping the tank for a clean ...

cheers

is it possible to reverse the wires to run the pump in revers ?

(hear this works for some types of pump ?)

cheers

My fuel gauge went awry about 18m ago...would not register beyond half way even on a full load of fuel...all continuity checks etc were OK. Was able to "force" the gauge to read "full" with the Faultmate test. This went on for 3 months and I was ready to replace the sender etc...

Came across the LR bulletin and on a hunch that there was crud on the sender I treated it with 2 doses of EFI cleaner to try and dissolve the crud...the first lot while filling the tank up to about a third full...and let it sit for a day or two then headed towards Rockhampton (700km) ...put in another dose while refuelling (full tank) . Both times used premium fuel...when I refuelled in Rocky.. gauge read "full" ...worth a try!

PS: the question I can't answer is ...why the crud build up? I suspect a couple of dodgy refills though I never knowingly used E10... (one of the worst pieces of public policy ever...that and the ETS,,,but that's another issue). The truck had been idle for a month or so prior with a 1/4 full tank while I sorted out the rocker/lifter issues...can only surmise that's when the bugs got to work and deposits began building up on the sender mechanism...
