Any Chevron fuel users notice drop in quality?

Marathon, Shell and BP have always run good in mine. I'm not sure whereSam's and Walmart get there's, but my wife filled up there and the car ran unbelievably crappy.

I prefer Arco now also owned by BP (British Petroleum). Maybe your car is not too happy with the Summer blend that we are forced to use to cut emissions. My 190E does not seem to have the pep that it has with the Winter blend. Peter.

Found out part of the riddle.They dropped the octane rating from 93 to

Yes, it's all the same no matter where you buy it...

Have you tried octane booster?I spent a small fortune on this for my once upon a time BMW E30 325e,but nonetheless did help!If you give it a try,go for Outlaw Octane booster.If I remember correctly,it will "supposedly" raise it 3 points.Or is there any truth to putting mothballs in the gas tank?Never was brave enough to try this so......

I use to have a gentlemen here in Kenmore washington that sold Avgas. Man that car loved it. You could put in a quarter tank of that stuff and fill it with regular and it would run like a monster...

Mothballs? I am not that brave either... Never heard of that before actually.

Some of the Octane boosters do work, but they are pricey.

Oh well, marty

Marty,do you know anything about this product?

Its octane booster and appears that link does not work correctly,see if this one works!

Whoa,did anyone see the fuel fragrance below the octane booster?What will they think of next?

Nutty! Thanks for the info, I think there is local seller of the "Red-X" racing gasoline....

Interesting you mentioned that...... Check out MBE that replaced it .... After the Feds required everybody to change out gas station tanks to fiberglass. They find out the additive runs thru the "pores" of the tank walls....and has its own side effects. On a regular enorgh basis to warrent a "disclaimer" on every energy bill ....it wasn't the oil companies idea to go to unleaded in the first place.Chevron if I remember carries the patent on that additive.....

Many of your octane boosters are methanol....

The mothballs if I remember correctly was nitromethane(model airplane fuel less castor oil) You can fry your pistons and tie crankshaft in a bowknot....but for a few minutes it will almost run as good as the model airplane engines.(highest performance diesel around and about the only two stroke diesel I heard of that didn't need a blower. )
