TowRig.com - Diesel Discussion and Tow Tech

trying to get an idea of what oil is used the most and why

goog ol rotella, cheap and tuff

I use Amsoil in Everything from my vehicle to my Generator and even my lawnmower. Great oil, tough, and my trucks run better with it. I have been using teh stuff for about 7 years now. Real hard to ruin it. Also, the ATF is almost impossible to burn. Great stuff!

i have either used Rotella or Valvoline Blue, no problems to date... :popcorn:

Rotella - Cheap

I luv da rotella

My honey is an AMS Oil distributor so that is what we use in everything from his tow rig to my DD to the ATV to the weedwacker.

valvoline blue extreme 5-40 and now trying royal purple 15-40
seems like the valvoline biulds oilpressure quicker and holds it better.....

I just switched from Delo to Amsoil. Curious if synthetic will make a difference.burnout

switched from rotella to mobil delvac

Quantum Blue!

Because oil specifications are changing, and not for the better. ( thanks EPA )

Because common PAO / Ester 'synthetic' basestocks have performance limitations.

Because the term 'synthetic' has devolved into a marketing term ( thanks castrol ), and isn't an indicator of a high performance oil.

Because cheap oil is..well.. cheap.. and you get what you pay for.

i use Amsoil in everything, especially my 6.0L little expensive up front for the oil and filter, but worth it in the long run. In my opinion anyway

Good call!waytogo

im assuming ford dealers use motorcraft when I take it ot them to change (warranty and all)

Rotella T seems cheaper than Delo 400 at walmart. is Delo better?

Don't assume that. They may be using the Motorcraft filters, and the cheapest version of that available, but they are not using the best oil available. Remember that the dealer's service department is there to make MONEY. Warranty doesn't pay. They buy oil in bulk from a local supplier and its whatever costs them the least, more for the profits.

I would prefer to use motorcraft. But you can never find it. So I use shell, a known good oil and readily available.

I use Schaeffer's 15w-40 synthetic blend. The fuel mileage in my last diesel went from 18mpg highway to 21 mpg highway. I like my trucks and my motor oil, super slick !!!!

Rotella and A quart of lucas stab.

ok all of you like your oil , but what experience do you have and can tell about the stuff you dont like

I have been and Amsoil user for 7 years now, and a dealer for almost 3. As a customer, I have had mid to high hp trucks that have never had a wear related issue. One of my best friends dad got me on Amsoil after witnessing his chevy half ton with nearly 300k on the 350 crank up right away every monrning. Since then I have used it in everything i have including my lawnmower.

Since then, I have done much research and testing. I have blown many people away with the torch test on Amsoil's ATF. Very interesting little test.

Bottom line is use what you like. Synthetics aren't for everyone, some people just don't understand synthetic oils and people tend to fear what they don't understand.

As for benefits, expect less wear, slightly better mileage, smoother idle and cooler temps in transmissions and axles. Expect to go farther between oil changes and spend less time working on your regular maintenance. Also, expect it to cost LESS than regular servicing with conventional oil.

I still can't find it here in the Mojave desert, even at truck stops. ANy idea when it'll be out?

The Shell Rotella is easy to get at Sams club in a 55 gallon can.

AMSOIL of course. I've run it for over a decade in everything I own.

I use Valvoline premium blue and have very satisfying results from it. Would not change at this point.

was using shell rotella but 5,000 miles ago i switched to amsoil 15w-40 syn and am pleased so far . the rotella would darken after 5,000 but the amsoil is still very light brown , very clean looking with the help of the by-pass filter . :) it cost more to get going with the by-pass filtration and oil but i will save money in the long run .

I run Amsoil 15w40 in both of our trucks and am getting ready to put Amsoil in all four of our differentials. I'm getting great oil analysis reports using the 15w40 as well. I used to run the series 3000 and didn't get as good of results but I'm very pleased with the 15w40.

Been running Rotella 15-40 in the spring / summer and Rotella 5-40 fall / winter. Always change around 4500- 5000 and always run Fram or M/C filter. Thats about it 4 1/2 years and almost 250,000 on it. [04 6.0 Lariat c/cab.]

hey diesel nut, I'm planning on switching to amsoil on my next oil change coming up soon with 5w-40 premium diesel oil API CJ-4. later on I'll change my trans and rear end with amsoil

Right on. On your 06 you should stick with the 15W40. The 5W40 is designed for the new motors, and you don't need to run that in your older motor. The 15W40 is a CI-4 oil instead of a CJ-4 and will work better for your 6.0L.

Also, I doubt it ever gets cool enough in HI to think about needing a thinner oil.rotfl

thanks for advice diesel nut

yea i know high 60s what was i thinking :doah:
