Large outfit that sells Honda generators, out of Kansas City, advises using premium gas (eu 2000). I never asked why.

My Tacoma works great on Magna - no such thing as pinging. License plate karma?

I am not a professional mechanic but if you have a vehicle that pings, I believe that you can change the timing to eliminate that.

pinging
on many newer motors you cant change the timing !! could be running hot,,bad EGR and/or its switching,, carbon deposits..running lean,,wrong plugs and
a host of other conditions.there is basicly two types of pinging and they are NOT good for your motor !!

I understand that. I was referring to the 89 Cherokee that has ping problems.

I would use what Honda says to use. My eu3000 purrs on 87 and Honda says use 87.
Of course, maybe that guy working at the outfit in KC has engineering degrees and scientific proof to refute the Honda R & D team. hahaha. Just
as I would take his advice on the best BBQ place in KC over a Honda engineer living in Japan.
My motorcycle runs fine on 87 but I use 91 because the book tells me it is best.

Yes, the 690 and the 450 will drink the 87 without farting, but I feed the 91 if possible.....
Like some folks, I would prefer an Indio over a Pacifico....but Pacifico will do if all else is not available 
Don't believe everything you think....

As an expert can you tell me why cars and trucks have internal combustion ENGINES instead of MOTORS?
I thought all motors were electrical and yet the propulsion system for boats, quads, motor cycles, generators, etc are called motors even though they
also use internal combustion.

Interesting discussion. I luv most of the answers.
I personally can tell/hear/feel the difference in how my boat runs when on magna, not great. Got a 150 yamaha 4 stroke that likes it when I run
premium through it and not magna. The difference is slight but noticeable to me. I get no pinging from premium and much less black smoke than with
the magna. This is also true on our EU3000i honda generator. Ironically, I can't tell any difference in my F-250 truck.
So I say, GO PREMIUM. I is better gas, sorry BOB...

Thanks Woody, I'll bring plugs and wires down next trip. The Jeeps stays in my garage down there. It was just my beach launcher because the brakes
didn't work. I bled the brakes and now the brakes are fine. So it has become my local cruiser too. Exploring all the washes and arroyos. That is
when I first heard the pinging.

brewer,
Which engine do you have in the Cherokee, the 2.5L or 4.0L?
Both engines were designed to run on 87 octane. However, that doesn't always mean that 87 is sufficient.
There are several problems that may cause your engine to ping with 87 octane.
Carbon buildup, running hot or in hot weather, improper timing, spark plug gap, etc. Does your Cherokee have a recent valve job? Surfacing the head
will increase compression and might require higher octane to compensate.
A tuneup might fix the pinging/detonation problem.
Do NOT continue to drive the vehicle if it is pinging more than momentarily upon sudden hard acceleration. Excessive pinging can cause serious damage
to your engine. Get a tuneup. If that doesn't eliminate the pinging, then switch to a higher octane fuel.
I have had more than one Jeep 4.0L engine that needed 89 octane to run without pinging. My personal tolerance for pinging is zero. A few cents more
per gallon is far cheaper than a complete rebuild.
Bob and Susan,
Please don't believe everything you read in those trite and brief consumer articles. Yes, I've read those too. Passing on that (mis)information as if
you have vast mechanical experience/knowledge is leading folks into trouble. Higher octane fuel is NOT simply a marketing gimmick.
Many vehicles are designed to run on higher octane. The manufacturer will specify the octane requirement.
Heavy demands on an engine, such as steep grades or towing, might call for higher octane than the manufacturer recommended originally. So can hot or
desert conditions. So can the internal condition of an engine or the engine tune. There are numerous variables.
I use what my engine is "happy" (zero pinging) with. If I anticipate pulling grades, towing, or in 95 F. + heat, then I will fill up with higher
octane on that tank of gas. |
Easy enough. Premium it is. I will be pulling grades up arroyos and driving in very hot weather. The Jeeps stays in Mexico. It won't be seeing a
valve job or head resurfacing anytime soon. I'll put new plugs and wires in it.
Thanks for all of your info.

All engines are motors. Not all motors are engines. Generally speaking.
