In that case, you're good to go (even back in '85, 15w-40 was approved by GM down to 10F in your 454). Enjoy the Delvac!

So since u seem like a 1540 fan, can you clarify this for me?

Is ALL 1540 oil the same rated oil (diesel grade)? I ask cause I think supertech makes a 5quart jug for like under $13 at my WalMart.

If this is the case, I think I'll start getting oil for the fleet here in a few days... I'll still check the rotella/delvac bottle for the ratings and compare it to the jugs they have but I'm just a tad curious to know NOW! lol

All 15w40 is not created equal. Just like passenger Car oil you have different formulations to meet even the same specs. Depending on her long you plan on keeping the oil in service, you would probably be well suited to using the Supertech unless you want to extend your drain interval otherwise you might want to pay extra for something stronger.

Here are some quick searchs I found.

Check the dates though some formulas might be different now just showing you examples of additive differences.

I'm a fan of the right oil for the application -- hence why I have 5w-20 in my 225,000 mile farm pickup.

You'll find that most of the mainline ratings (API, ACEA, Caterpillar, Cummins, Volvo, etc) will be identical, with a bit of variance on down the line -- for example, Rotella carries JASO MA, whereas Delvac sports the CF-2 approval.

Super Tech 15w-40 is a fine product, although unknown beyond what you see on the label (Citgo, Warren, or whoever was the cheapest source at that time could end up bottle) -- if I were trying to go with the lowest price possible for whatever reason, then I'd pick up some large jugs.

With that said, for your applications, I'd still select Delvac. It's a solid, well-known product (great base oil/additive package) at a really good price.

Mobil Delvac 15w40 is spark ignition rated "SM".

I've decided between delvac and rotella, now, my only issue, i might go rotellamjust so i can get the bbiigg 5gallon bottle!

But i might just buy delvac and forget about it....


I'm totally for (right oil for right app )to, but i own nothing new enough to be crucial to run the correct viscosity...

I may, say i needs be picky about Mt f150 only wanting 5/30and being a 97... that's my newest motor with under 94xxx on it...

What temps does a diesel run at? Or the temp the oil is rated at to endure the shear resistance? I'm thinking about switching to 1540 in my 110ci Harley motor that gets oil 270at its peak and regularly sits at 200/250

Delvac, Rotella, Delo 400, & Valvoline premium blue are ALL good choices for your 454 in hot climate, I've ran several big blocks with HDEO with no problems, Probably OK in your Harley, But maybe someone with more air cooled engine experience will chime in.

I would stick with a 5w30 on the F-150.

I'm really thinking it.
15wt is 3times higher then what she calls for, might be too much too soon

Picked up 2 gallons of rotella t 1540 and a Purolator oil filter...Poped the lid on the rotella and that stuff smells wicked.... it reminds me of the (Mobil 530 clean )that I bought a long time ago...

Next trip. I'll be buying the 5gallon pale, maybe...

I'll change the Volvo oil today and start it tomorrow morning before work.

15wXX is not 3 times thicker than 5wXX oil.

Isn't the base number for dinosaur oil the actual weight of the oil being used? And the determination of how strong/weak the oil is?

My Harley manual showed something about the larger varying numbers between cold start and temp rating the weaker the oil...

Im still unclear about multi grade and its make up. My first bike was straight weight 60 so I had no worries about thinking about oil lolololol

I just don't know how much my 90k mile f150willmthank me if I jump from 5w30 to 15w40.which feels like 2050 gtx imho

No. The base number or TBN tells you how much life your oil has. It measures an oils ability to neutralize acids over your OCI. The base number does tell how strong an oil is based on that. This is completely different than base oils. Base oils or base stocks are different groups of oil to make motor oil. An oil gets it weight from flow properties and viscosities at 40c and 100c. You should read motor oil 101 on the home page.

Sorry if this was answered already, I only quickly skimmed through before posting. What vehicle has the 89 350tbi? And how many miles are on it?

I have an 89 Camaro with a 305tbi... I'd not run diesel oil in that engine. My sig shows that it has PYB in it now, but it has used other brands also, but all were gas oils, not diesel. I'm not saying you shouldn't run diesel oil in yours, but it would probably be better off with 5w-30 API SM or SM oils, rather than a diesel oil.
