Oops! Made a silly mistake! I've known for years that my car is not suited to E10 fuel, but whilst on holiday after a long drive to a country town, I foolishly added 36 liters of this fuel type to my carburetor classic. Yikes! It only has a 50 liter tank, so still had about 14 liters of premium unleaded in it. I also added 50ml of valve saver additive ( Flash Lube), as I usually do with each fill.
So, I've read that it could really stuff things up, so am wondering if this once-off incident will cause major calamity? Will I make it home in one piece?
Should I perhaps keep adding about 10 liters every 100 kms to dilute the ethanol component even more, or should I simply symphony it out altogether?
Thanks in advance for your invaluable assistance.

I think i'd continue to dilute it!

Does it seem to be running still in a lovely way?

I've been running it in both of my jeeps (1977 and 1946) it's pretty much the norm here to use it, few places have non-ethanol and it's more expensive

The only problem i've had with it in the many years i've run it, is if you let the car sit for a long time, it'll really rust up the fuel tank! Case in point, my 1946 willys jeep sat over the winter, I had a heck of a time cleaning it up and I had to change quite a few fuel filters! The other jeep has a plastic tank!

This year I ran "willy" nearly dry, then added a tankful of non-ethanol before he got parked for this winter (on nice days, we will battle the cold and go for a ride anyway!)

I have a holley carb on my '77 and a solex on the '46, thus far i've had no problems with it "eating" the rubber stuff up

I fear

That everything will be fine on your car!

Your turn

Hiya! I am pleased to report that my Little Red Rocket was able to use up the entire tank of that pesky E10 fuel without so much as a burp! I have since refuelled with the regular Unleaded Fuel, inc. Valve Saver additive, and she is zipping down the road, lickety-split! :)
Infact, even after a very long open road drive in the heat, she actually DIDN'T stall at the lights when we hit town again. As has been her usual habit in the past! She's idling at a lovely purr between 1,200-1,500 rpms - her preferred setting - and I am quite relieved she has found her 'motoring mojo' again! She's approaching 38 years of age, and I've had her for almost 27 years. My patience and TLC has been vindicated. Phew!
I do still have her Universal Joint grumble to deal with. Eventually. Which only occurs between a speed of 60-80km/hr, after 80km/hr she settles and hums along nicely. Now that I have been reassured by TWO experts (yourselves, and my own veteran Toyota mechanic), that this grumble won't be a safety issue but more a comfort factor which may in fact soften in time. I can await addressing this until her next proper service. Due in a month or so.
It's Summer over hear, and she's very much on active duty during these warmer months. :)
Thanks again, and happy/safe motoring.
JS ;)

We're happy

That you are happy!

I knew you would be just fine

You're running neck on neck with my '77 cj-5 (the tan one)("mr. Jeep")

But you have a ways to go to catch up with my '46 willys army jeep ("willy")!
