AmsOIL 15-40 diesel motor oil,consensus?

[hood latch]

Hi Folks:

How about some opinions on this oil for the 6.0
I put about 10,000 miles per year on my 2005, about 1000 0f which is pulling my 6000 lb. camper.I was thinking that I would change the AmsOil once a year with a filter change @ 6 months.

Other than the obvious benefits of synthetic during extreme winter cold and high summer heat, I am thinking that the synthetic might help to keep the "oil fired" injectors from having oil related problems.

I would appreciate any feedback from those who use or have used the AmsOIL, as to their opinion. Why they like it, or why they don't.

Thanks.......Hood Latch

I've been considering a very similar strategy. I just ordered up a couple cases of this stuff Series 3000 Synthetic 5W-30 Heavy-Duty Diesel Oil

My plan is to change it now. Change it again at 4K-5K range and then I make a decision dump again one more time at 5K or go to a 10K rotation with a filter swap in the middle and an occasional UOA. Not sure which way I will go yet.

The reason I change it again at 3-4k is because there is going to be a good amount of used dino oil left in the motor when I do the initial swap. I like to get that out of there before pushing the miles up.

Amsoil is a great synthetic oil. You can't go wrong with it. If you want to stick with a 40 weight go with the 5w40 instead of the 15w40. It will help with your cold starts. The HEUI injection system shears oil badly but UOA suggests it stops shearing when it gets to be a 30 weight. Currently a number of folks are trying the 30 weight strategy like bfrank below.

That's the good stuff. Good choice and a reasonable strategy. For sure get a UOA before trying to push it out to 10k. I'll be doing the same thing when I change out my current load.

Oily analysis is the best way to find out what oil is for you and your truck

I think your idea is on the money. If all you do is about 10K a year then a AMSOIL and a filter change midway threw is great. The SDF88 is good for about 7500mi but nothing wrong with playing it safe and changing mid way. You could do Oil Analysis and possibly even run it longer to save yourself even more money.

With AMSOIL 5 and 15w-40 you are getting some of the best protection for your motor. Both oils stayed in the within the SAE rating in a shear stability test where the others fell below that rating. Granted this was based on fuel dilution but that is one of the worst things that can happen to your oil. AMSOIL also addressed the HEUI systems and the known problems of shearing oil and both 5 and 15w-40 oil can with stand the shearing effects of this system. If I may get you information about either of these please just let me know.

I use Diesel Concentrate and Cetane Boost every tank. These were the first two products of AMSOIL I started using. Both products did what they said and so I took a chance and started using motor oil. Because of the gains I saw and the product doing what they said it would I became a dealer. The 5w-40 is what I run because I drive my truck daily and was looking to get the best fuel milage I could. I have put 10k on the oil before my first oil analysis when the report came back all was well and I pressed on.

If I can answer more questions for you or get you information about buying AMSOIL products at wholesale please feel free to PM, Email or give me a Call.

Thanks

What year is your truck? With mine being an '05 I ordered the Series 3000 Synthetic 5W-30 Heavy-Duty Diesel Oil (HDD) because that is what it seemed would be the correct product for my engine.

Big Ol Dog,

Thank you for the feedback. I did order the AmsOil 5-40W. I have on hand, two FoMoCo filters (showing my age there, huh) when they are used up, I will try the AmsOil filters. Thanks again.......Hood Latch

I have an 08 don't cuss me Chevy. There is nothing wrong with you choosing 5w-30. What climate do you live in? Did you chose the 30 weight because of the shearing with the 40 weights in the HEUI systems? If you go to the AMSOIL site and do the product look up for your truck the first suggested oil is 15w-40 AME.

If you have anymore questions that I can answer please feel free to ask.

Thanks
