What oils are good without having to sell the house.

[freightliner009]

I'm in the middle stages of a complete rebuilt of a 7.3 and wondering what kind of oil to use. The shell rotella was always in it for 243000, a choice? What about the new rotella t6 5w-40. Or is the price not worth it. Thanks

I have ran both the regular rotella 15-40 and T6 5-40. this past winter we didn't have crap for cold weather (I don't think I ever plugged my truck in) but I noticed a big difference in cold weather start with the synthetic. and for the extra few bucks, I've been running it since

I just bought my '03 last september and had to jump straight into winterizing the truck for cold starts. Although just like Matt, Wisconsin had an unusually mild winter (maybe saw -0 a couple times at most.) But I ran the Rotella 5w-40 and the truck fired right up without plugging it in, even after sitting in the wind for 8-10 hours while I was at work. It's the only oil I'll be running with this truck.

You're familiar with the company Monster (as in Monster Cables)?

They make High-End electrical stuff and the like and are primarily made for people who want to feel special.... (they've got the really Good Stuff, the Donald Trump stuff, because they want to feel good about themselves and how much they care about what they have ). And, for a mere $150, they can have a HDMI Cable with no equal! (or so it makes them feel,,,, again, it's All About the FEELING)

That's what you have with All sorts of products for your car & truck.

Amsoil, Schaffers, Royal Purple, Lucas, all that stuff is Much more about YOU than your engine (just like those who change their HPOP res oil)

The simple fact is, as long as you change your oil regularly, it's not going to make One Bit of difference what you put in there. Delo, Rotella, Quaker State. Pennzsoil, Whatever,,, as long as it meets your engines requirements (all in the Owners Manual) go ahead and use it!

Don't let some sheep bahaaa you into believing your doing anything but the "Slow-Stroke" when opening your wallet and overpaying for an oil product...... (unless you've just Got to have that HDMI cable )

regular rotella is fine, but if I lived up north, I'd probably switch to the synth 5/40 for the cold months

I like schaeffers 9000, because its the cheapest 5w40 cj-4 oil I can get at the moment v. M1 tdt and t6. If you don't live where it's cold, regular 15w40 is fine.

I know you're nowhere near Atlanta but I just changed my oil with Conoco/Phillips 15-W40 Fleet Supreme EC that I bought from Atlanta Fuel Co. for $41.20/4-gal case.I had the guy there send me over the spec sheet and it turns out it had a total base # of 9.5. I have been told that this is the same oil as the Motorcraft oil. So far so good but I only have about 500 miles on it. I figure it will be good for 5000 mile intervals. I still use the motorcraft filters though. Total oil change $56.

Here is a very interesting comparison. Read the whole article then decide. I am using the Valvoline Premium Blue.

Rotella T for warmer temps, T6 for colder temps. I don't eveer use T6 but it doesnt get very cold here and my 7.3 runs fine on the 15-40

I agree with Ralph, it depends on your driving situation. It is always helpful to look at numbers because they dont lie. This is from a virgin oil sample. BTW this site is great to read up on oils:

Delvac 1300 Super 15w40 - Bob Is The Oil Guy

With that being said, i run Mobil Delo 1300 year round here in Nashville. Buying it in 2.5 gal jugs is helpful also.
