Premium Petroleum
Just wondering what the prevailing wisdom is on running higher octane
fuel and/or synthetic oil in a vehicle that sees off road use, if it isn't really required by the manufacturer's specs. Is it worth the extra $$$? Does this help in some way to offset the extra wear and tear we put on these vehicles, or is it a waste of money? (Please respond or I will be forced to retitle this message "Premium Petroleum = Junk!" to elicit more comments. <g>) |

One my 86 CJ7 with the 258 carb engine set up manually I have more than
a 100 miles per tank difference between 87 and 91 octane and a serious high speed power difference. On my 88 Cherokee 4.0 engine, no difference.

If your engine does not have a knock sensor, a higher octane has no effect on horsepower or mileage that cannot be accounted for as well by simple brand to brand or batch to batch variations. Disclaimer that anecdotal reports of superior cleaning abilities of higher octane exist from credible sources. Note that this applies if your engine does not ping on the cheaper octane, with a suggestion that if it does ping slightly on the highway under load, stepping up a grade to inhibit this under heavy climbing is extremely cheap insurance. If you are driving heavy off road, you need to change oil more often, particularly in the desert, whether synth or dino. However anecdotal reports of better mileage from credible sources exist that a synth or synth blend does help with same. Or you could retitle the posting "Yet another boring repeat of the same old thread... " |

Synthetic oil, yes. It holds up better during heavy use.
Premium gasoline? Haven't heard of that one. My 90 and my 98 were both designed to run on 87 and do that just fine on and off the road.

I'm not a fan of synthetic oil in jeeps, unless its been run with synthetics since the first oil change. Switching to synthetics on a vehicle with a few miles may result in maddening leaks that you didn't have before. Also, its hard to justify the increased cost, especially since offroad use introduces dust and other contaminants that aren't issues on street cars, and which will require you to change oil more often than the extended frequencies touted by the synthetic manufacturers. My advice is to stick with dino oil, and change it every 3,000 miles. Robert Bills KG6LMV Orange County CA http://www.outdoorwire.com/4x4/jeep/...p-l/billsr.htm http://www.RobertBills.com |

Seriously doubt it, although a good synth may hold viscosity better at high temperatures and load. Also seems [judging purely from the notoriously inaccurate guage] to hold pressure as well in desert temps.

Re: Premium Petroleum
I'm with Mike on this....the higher the octane the more timming you can run. I
don't run much advance....Just tune it for mid grade. I can feel and see the difference at hwy speeds. Thats my take on it.....now if your running with new OBDII and engine management systems higher octane aint worth a crap......run what the factory says. The oil I think is a toss up....I change the oil in my Jeep every 2k with dino. BUT I use Mobile 1 Synthetic in my Z28. Thank god I only drive it a few thousand miles a year cuz its $40 for a driveway oil change. Brian 88 YJ |
