To run one of those cut rate oils is just dumb. Every mechanic I know says "Oil is the cheapest thing you will ever put into your motor" and they are right. I will also never run a Fram filter, but that is another subject altogether.

Many learn this the hard way. I use WIX , or Fleetguard. For oil I run Amsoil.

Thanks for posting this information.
Those cheapo "off the wall" gas stations are selling gasoline made in back yard stills. One day they are making Shine and the next they are making gasoline, best to stay with major brands. I think all those Costco and Walmart stations are selling "home made gasoline".

I've never heard of nor will I use any of those oil brands anyway.

Thank you for the information about the oil and the zinc additives. I reciently purchasedd a rebuilt engine for my '91 f-150 from a firm in Texas. They put new upgraded everything in that engine, even line bored the crank and cam. What a beautiful job they did. The mechanic who put the engine in for me said to go purchase the zinc additive and put it in with my oil but didn't say anything about putting it in with each oil change. I do run synthetic so I am sure you are right about adding it (or some) to every oil change. I will do that from now on as I sure don't want to be purchasing another engine for this truck...GREAT ADVISE, THANK YOU...

As I stated earlier, call me crazy or whatever . . .

Granted it has been at least a decade now but I tried using "off the wall" gasoline in my '86 Jeep CJ-7 a few times and after one tank or so it started acting up, primarily on the initial start-up.

Using Shell V-Power Premium seems to fix the problem . . . maybe the Jeep is able to "read the pumps" or just prefers Yellow, whatever it is, I'm convinced there is a difference.

Use a good oil. Send in your used oil sample to a lab. Can't go wrong.

Ok. You're crazy. Gasoline is mingled at the bulk plants, purchased across brands and different refineries, and then purchased by the local station or franchise at the lowest price point possible. It is shipped from a bulk carrier or fuel farm that services multiple brands. If a station is a Shell Oil company station (not a franchise) I believe they are still using their own additives. Other than that, all bets are off.

Specific issues related to a specific vehicle can probably be diagnosed to a problem in the vehicle. I doubt gasoline will end up being the enemy unless there was some water or contaminants in it.

A bigger issue is likely to be buying from a station that sells smaller volume and the gas may sit longer or may get contaminated in the tanks. I would propose buying from a station that does high volume and ignore the branding, as it is not related in 90%+ cases to fuel quality.

Talk to the guy delivering the gas to a gas station. He will tell you the truth about where all comes from. Additives are added after his tanker is filled with brand X.
