I'd never buy "Thrifty" oil for my car. I wouldn't when I was in high school and it said 30W right on it just like Castrol. Oil may be oil but I paid 4 times more for the name brand.

Why not? Have you ever herad of a petroleum company called "Thrifty Oil"? Probably not because "Thrifty" oil is bottled by Mobil or Shell or other ?????? and just put Thrifty's name on the bottle.

Mobil Oil refinery order desk:

"Hey, Jack! That batch of 500,000 quarts of oil, run 400,000 into our bottles and 100,000 into the Thifty's."

I buy whatever's on sale. Never had an engine failure yet due to an "inferior" oil in 40+ years of owning/maintaining vehicles.

No short cuts on the oil and oil changes....Think how much you Love your Z......

Lol, I love (saving) my money more. But hey, it's your $.

I just do not trust it. It is the or other ?????? that concerns me. A complete unknown. I assume then in 40 years you have used quite a bit of Thrifty oil as it is the cheapest, and no problems. Or what is cheaper than Thrifty if I might ask?

As long as you are using a good-quality oil/filter and change often, the differences are negligible for a DD. Some may be slightly better than others but even the "lesser" ones are more than good enough. I still like to put "the good stuff" in my car, but I don't get obsessive about it.

I run Mobil 1 Full Synthetic with a 1/2 quart of Lucas Oil oil stabilizer into my DD, non-tracked Z with 40K+ miles. I know the flaming is bound to start because I'm putting "snake oil" into my precious Z but I have a reason for it. :stirthepot:

Many moons ago I had a 1984 Honda Accord 4 door with 130K miles on it and I was running the full dose of Lucas Oil stabilizer which did in fact keep the small amount of smoke it was puffing at bay. Without my knowledge my oil plug fell off or was taken off sometime between my weekly oil level checks. I checked my oil level and it didn't even wet the dip stick. I looked under the car and saw that the drain plug was gone. The engine temperature never increased, the engine purred quietly the whole time and there weren't any oil puddles on my driveway. I continued to use Lucas Oil until about 225K miles when I gave the car away to a relative. I was running the cheapest oil on earth at the time since I was only in high school so I have to attribute the miraculous survival and longevity of the car to the Lucas Oil stabilizer.

Andy Granatelli (STP) was one of the greatest hucksters of all time, and set the stage for many subsequent generations of oil-related hucksterism.

Are the 24 bottles of Slick 50 I purchased a waste? Is that what you are saying? Well? Are they????

:icon17:

Nah, it wasn't the oil stabilizer, it was just an old Honda. Those things never broke.

I'd keep them. They would likely work very well in your car that runs on water.

I like the way you think. :tup:
