I've posted this before. Maybe it no longer applies?

With a 15,000 mile oil change interval guarantee so it's actually cheaper if you pay to have your oil changed. Oil changers service change is $55.00 here in wisconsin so there. If you don't believe in the warranty or the quality of the product, you are just misinformed. I thought it was BS until I ran it and had it tested by an independent company that analyzes oil for over the road trucks. It's superior to any other oil available.
On top of that, I ran it 120 k miles in a POS Kia Rio . Small 4 cylinder, short trips ( 35 miles max),15k oil and filter change interval and it never used a drop of oil nor did fuel mileage vary. 4.5 quarts in and 4.5 quarts out.

Read somewhere Rotella has had some of the good additives removed now.
Good additives removed? I think this may be correct for the T4 and T6 versions. The one I have is the Rotella T Triple Protection version. That product may no longer even be available. I was recently offered a deal on it so they could get rid of it, but had to take all 4 cases the place had for that low price. I took it. But sounds like the T version is good to go.
BTW, it appears this problem does not just apply to vintage cars. Same applies to cars, trucks, tractors and a whole slew of other old equipment, most of the owners of which are oblivious to the problem. They are dumping in either what is cheap or latest greatest and assuming it's OK. The higher zinc oils needed for the old engines with flat tappets, and which do not have catalytic converters and such. That is nearly all of my stuff.

i remember back in the 70's a fellow i knew bought a brand new olds .He never... ever changed the oil but
did add oil when required. He traded the car in at 50,000 miles, it ran ok and didn't smoke. I can't imagine
what it looked like under those valve covers?

I would think that anyone running a 340 with a flat tappet cam wouldn't CHEAP OUT on their oil. 318 maybe. Wait till you dumb asses flatten a cam, then maybe you will see the light. And NO, O'Reilly oil with a bottle of snake stuff poured in on top probably won't cut it.
I think somebody mentioned in this thread somewhere that VR-1 10w-30 is at Walmart for 26 bucks a jug (5 qrts). That's as cheap as about any other jug of oil. Whoever suggested this route, I'm going to have to agree with him!!

So you know the 3 gallon is in a box with a bladder not jugs. It’s just less convenient.

Sounds like wine in a box!
Thanks, I just ordered 3 of them....with free delivery today! SCORE! Now I need filters.

Here's what recommended in my 84 D100 Owners Manuel. I'm in Florida, so I use the 20/50.
The chart basically says that any grade oil 10W30 to 20W50 is good for high ambient temps. The upper ambient temperature is irrelevant as the only thing that matters is the engine temp which is the same regardless of ambient unless you're engine is over heating. The oil grade recommendations change based on the expected low ambient temperatures.

I mix peanut oil and wheel bearing grease, smells terrible and doesn’t work, but it’s what my granddaddy used in his f150.
Another VR-1 user here. Every 3,000 in the old cars.
My TDi VW’s are on a 10,000 mi interval with the VERY specific, high dollar, oil and the long life filter. I change at 8,000 though.

Good grief you really popped a memory with this. Back when the used car market jumped into a new gear and a local Ford dealer wanted to also offer a warranty of sorts, I was their 1st UCD pre delivery tech. Once in a while a customer/buyer would approach me, "What type oil do you recommend for the Thunderchicken, whatever they're buying ?". Me, I don't care if you put baby oil in it so long as you keep it changed. When you can't see the markings on the stick through the oil, change it. Yep, I was quoted. UC manager told me "no more talking to customers".

Between the 30 and 20w50 which do you think seems better? 7000rpm blast was eith 30 or 20w50? Just curious since I've only ever used 30wt straight in my 360 dodge dart sport. I've considered using 15/40 or even 20w50 just never have. Seems to be happy with the 30wt.

Engine Masters did a show on hp vs oil weight. I suggest to anyone to watch it. You might be surprised. No, I’m not giving up the answer but I will give the link.

This is a recent story about STP oil treatment. I have an 86 mustang 5.0 with the low oil indicator and I suspect I need a rear main seal etc as that was common on 5.0 Windsor Fords. I can top the engine off drive it a short time say a weekend and the low oil light comes on. I added stp recently and it has went alot further and the oil level hasnt dropped as fast. Im not sure what that stuff does bit i think it did something it is thicker than molasses though its like real heavy slow moving oil you pretty much have to turn it up in the oil fill and walk away for 15 minutes.
