Re: What kind of gas?

ah........but do they - or should they care, as long as it gets in the right hole?

I thought more or less everybody was starting to use alky as the MTBE is being phased out. Or have they found something even more toxic and foul tasting than MTBE to replace it with?

Regular gas should be fine.

...and if it isn't just add a bit of cascara extract to each tank.

I confess that I bought a couple of tanks of high octane this summer while I was struggling to pass the Smog Check dyno test, but I have no real idea whether or not it made any difference. I would like to run the test with both high and low grade gas, but that would cost money so it's not gonna happen. Anybody try it?

Replacing a nonfunctioning EGR valve definitely made a difference.

I can imagine several possible advantages.

I can imagine that an motor that was designed for regular gas that has 100K+ miles of wear, with some carbon deposits, etc. might knock a bit more than it was designed to, giving an increased NoX reading on the smog check. Even with a new EGR valve I read slightly above average.

I can imagine that such a motor running regular gas might knock enough for the computer listening to the knock sensor to retard the spark enough to reduce milage. I can imagine that the effect of that might be greater % than the price increment to go to a higher grade.

I can imagine that the motor was designed to run on regular gas, but that the crap sold for regular gas with MTBE to poison the Calif ground water in it, federally subsidized Archer Daniels Midland EtOH in it, and who knows what else, just isn't good enough. I can imagine that a company like ARCO might be blatantly lying about what the octane rating of their product really is.

I don't know what of those to believe, but there is nothing wrong with my imagination.

mabar doesn't C what I am saying. Heh. KH

LOL!

I got it.... ;-)

All of this could be true, but it is not in the context of the original question, which came from a guy that just bought a Jeep an dasked what kind of gas it needs. The correct answer is that it needs Regular.

Now, the variation on that answer is that some people might be tempted to put High Test in for a road trip, and I conceed the point that there could be some obscure advantage. But, the people that actually test these kinds of things say that even for a road trip, there is no particular advantage of using Premium fuel. This brings us back to the first correct answer, Regular is what it needs.

--snippy--

If it even has a knock sensor. Newer Jeeps apparently don't have them. They rely on the computer to provide the correct timing based on various sensor inputs, which do not include a knock sensor, and based on the assumption that the engine is getting the correct octane fuel. Your friend's engine could actually be pinging constantly, but just below the level where one would hear it. That of course is not so good.

There are a goodly number of non-Jeeps on the road. And you don't really think a real Jeeper would be this errr..... stupid. This particular car is a Honda.

It has a knock sensor. And a not particularly bright owner, IMNHO.

You have a special case with CJ though, just as I have a special case. The original poster asked which gas to use in a TJ with a 6 and an automatic. He needs regular.

Yup, for sure like I mentioned with my Cherokee.
