Seeking additional info abour repairs to a Jeep

LOL - how old is that?

You are right, we get the 87 too.

Try it on a highway run and compare. If you get better mileage, then compare the amount like I did. On our 88 Cherokee 4.0, it shows no benefit.

My owners manual even says to use high test when fully loaded or running hard.

Maybe I will then just to see. I was always afraid to feed it some in case it decided to get used to it and then thumbed its nose at the regular Citgo stuff I use (from Venezuela - not the arab regions). I suspect that I will see a result similar to your 4.0. Tomes

In some states and/or some retailers will add the alcohol to the higher octance blends. I talked to a retailer, the alcohol blends have the same cost for higher octane. One local dicount place has 87, 89, and 91 octane, 89 and 91 are the same price.

Downside is that you get appreciably lower mileage. I just did a cross country trip, I get almost 2 miles per gall> Here in the states (NJ anyway) we get the averaged 87 for reg, 89 middle

It is what shops that don't first check the valve cover for leaking will change rather than replacing the valve cover.

IF your valve cover has been replace by someone who knows how to tell the difference between a genuine rear seal leak and a valve cover leak, and you then would need to replace the rear seal, might as well get this one done at the same time.

"Injection cleaner ? If it has never been done *and* you have a preoblem indicating a possibly dirty injector, it could be worth doing. Otherwise it is a really good profit center for the shop.

Since Bush Gas, I haven't been able to run Texaco, Chevron, or Shell regular in a 95 4.0 without mild ping. Recently the local Valero station ran out of midgrade, and it seems that their regular will actually run without ping.

I can show records for multiple vehicles over the last 15 years or so that show a consistent 10% drop in mileage for the 6 months or so we are required to use the blended stuff here. That's a composite of long highway miles and local puddle jumping. In the short term, the same figures seem to hold true when I fill up with the blend in Colorado to drive to Texas. I get a consistent 10% decrease no matter which octane level I choose in my 88 4.0. Funy part is that going south and east the prevailing winds are out of the NNW so I'm going downhil with a tailwind on the way down while on the return I have a headwind going uphill - and still get better mileage!

Follow your owner's manual when choosing octane grades... it was not the brand, I'm=20 betting. __ Steve .

It was the additives I am sure. It has happened before.

I was running hot, hard and fully loaded and in those circumstances, my owners manual calls for high test. My owners manuals both also forbid any alcohol mix of any kind unless you need a little to get to real gas.

I also have a modified engine set up manually like a 1981 engine would be with no computer controls and the minimum pollution controls.

It only happens with brands that have that super cleaner in them or too much alcohol, other high octanes like Esso work great.

I remember gasohol from back in the '70's/early 80's. Smoothest burning stuff since Esso Extra and Gulf NO-Nox! No loss of mileage in my '65 IHC Scout, and never any water in the gas, either. It kept the fuel system squeaky clean, too, and gave a decent octane boost. (Change the fuel filter after the second tankful due to all the trash it removes.) It was a mixture of gasoline and 10% anhydrous ethyl alcohol (ethanol). The oil companies hated it, and launched a short-lived misinformation campaign against it. But drivers loved it.

I must say that the gasoline sold then was different-the stuff we buy now doesn't even smell remotely the same. I often wonder just how much real gasoline is in a gallon of fuel now. Real gasoline is primarily a mixture of n-heptane, octane, and nonane. BTW, all the racing alcohol I've seen (and, admittedly, that isn't much) is methanol, which is hard on rubber fuel line components but is about the highest octane fuel around. It is often mixed with other fuels, and those mixtures require a lot of modification to the fuel system.

After any jeep repair be sure to screw all parts back together with wing bolts. (G)

The closest I ever came to being a farmer was working on a catfish farm one summer while in college. Unless you count a small beekeeping hobby a number of years back! Sweetest tasting hobby I ever had! :)

The ethyl alcohol limit in gasoline is 10%, you can only use 5% methyl (wood) alcohol.

Methanol is cheaper and also is exempt from Revenue Tax because it is not drinkable.... well.... you shouldn't drink it as it is poisonous and will blind you...

Methanol is also harder on the plastic and rubber components of your car but I am assuming that the makeup of the parts now is impervious to alcohols.

By destroying your optic nerves. And just slightly more will paralyze you, and a slight bit more than that will kill you outright. It's vapors are also poisonous. It is also used as a paint stripper.

So far as I know, there was no alcoholic beverage tax on ethanol produced for use as a fuel back in the gasohol days. I do know that producers had to detail their procedures to keep people from drinking it in order to get a permit to make it.
