Technical Who runs Shell Rotella

Hi fellas
Who uses Rotella 15w-40 in their V8 engine?

 

me

 

me 2
T4

 

Been running it in my roadster for 14 years

 

Me

 

I'll run it but not without a ZDDP supplement. This has been well documented here and other places, Rotella is not the high-zinc oil it used to be. Other than that, I've switched over to Valvoline VR1, which is supposedly better for flat-tappet engines.

 

I run 30 weight Rotella in my 46-48 Flathead engine in my 34 with a little Marvel Mystery Oil.

 

One thing that is overlooked by many is that there are several versions of "Rotella" with different specs and additives- have to get the right one for your usage

 

Me does

 

No reason to, why would you ?

There are PLENTY of hi quality of "automotive" oils on the market !
Diesel oils have different requirements than do gasoline burning engines !

Today, a non-issue. Diesel oil for diesel engines...and gasoline oils for...gasoline burning engines...period..!

Always use oil.
Oil is good.
Change it every now and then.
Check it from time to time.

 

My Pontiac loves it

 

I also use Valvoline oil in my 383 stroker motor & change it every 6 months...........

 

I have been using Rotella in all my hot rods for many years. I guess the newer oils are OK to use with flat tappet cams and high rate springs, but I am a creature of habit......

 

I use to run that in my powerstroke diesel

 

I’m south of the Mason Dixon line so I use erol. Rotella erol to be exact.

 

Used it in my diesel pickup for years. Valvoline VR-1 in my flat tappet Hamb cars, quality oil in my OT roller cam engines.
Agree with Mike, diesel oil for diesels, car oil for cars. Different additives.

 

I am in the same camp!

Both of my Duramax Diesel Transporting trucks get Rotella T-6 5W-40 full synthetic & basically always have, all of my classics, hot rods, etc get Valvoline VR-1

By the way both Duramax Diesels are over 600,000 miles each on the Original engines & transmissions. They only use about a quart every ten thousand miles (which I think is about perfect)

God Bless

Looks pretty good IMHO.

 

I do to

I run 15W40 weight Rotella in all my carbureted engines. Always with a little Marvel Mystery Oil. I put that $hit in everything!

 

Those who say " diesel oil for diesels, car oil for cars. Different additives", can you elaborate on that? What are the differences in additives between the 2 types, and why is car oil better for cars than diesel oil?

 

Is it that time already?

 

I’ve used rotella 15-w40 in my old cars for years

I’ve also used onco 10w-30.
“Performance” 10-w30
“ Bos” 10-w30

and a multiple of “no name “ oils in my old cars . Pretty much anything I get at work for free I’ll dump in my crankcase .

the amount I drive and I don’t drag race or beat on my cars and frequency of my oil changes I don’t think it really matters . I used to run good name brand oil .

unless it’s a high buck engine or a race or severe duty application it does not matter


@anthony myrick said it best in his post , keep it clean , keep it topped up and your good.

I change my oil and filter in the spring . Then I dump the oil mid summer and do another oil and filter now in the fall . Pretty much every 3 months the car gets new oil .

 

4 quarts, a bottle of STP for good measure in the 250 in my 36. Been doing it this way for years. Mitch

 

I do to

 

I recently went to buy some oil at the local AZ., and asking the manager about Brad Penn oil. My new daily driver has about 105K miles on it, and thought I wanted some oil with moly in it. Long story short, his brother-in-law was in there talking with him, who is/was involved in NASCAR. He tells me that no matter what it says on the car, they all run Mobil 1. I tried it, and I have noticed at idle the oil pressure isn't as high as it has been, not bad, just about 5 psi.

 

Which one? There are 13 different Mobil 1 brands, and in each brand there are multiple viscosity grades available. Which one do they use in NASCAR? Which one did you use? Why that one? What did you use before?
