Synthetic Oil

[kevin21]

I don't mean to span the board so be nice.

If you guys use synthetic motor oil, which do you use. I seem to see that there isn't a consensus when searching the board.

Can you use Mobil One or a 40 weight of any kind? I used to use Durablend in my Dodge but it was a gasser.

Stick with a true diesel oil.

I run Mobil Delvac 1. Amsoil 15w40 HD Diesel/Marine is also an excellent choice.

Mr. Kennedy's right - use a motor oil formulated for diesels. There are compelling reasons to do so.

I use Amsoil's 15W-40 Synthetic Heavy Duty Diesel and Marine Motor Oil. I have used different Amsoil motor oils in all the different vehicles I've had with excelent results.

I use Amsoil 15w40 Diesel oil also. My local Chevrolet Manager told me that Amsoil is about the best there is!

Great thread.

I just signed up for the preferred Amsoil buyer's program and had similar questions.

What's the consensus on using synthetic oil in a new DMax [<4K miles]? Should I wait till I get 20-30K? Amsoil's dual oil filter setup will extend oil changes to 10's of thousands of miles and recommend to switching to oil analysis rather then scheduled oil changes. Does anyone here do this?

I was thinking of switching all fluids [diff\trans, etc.] to Amsoil at around 5K miles.

Kevin,

Mobil Delvac 1. Make sure you get Delvac, there is Mobil 1 synthetic that is sold in Wal Mart that is not diesel oil.

I read here not too long ago that there is now a consumer version of Mobil 1 formulated for diesel use. I have not seen it myself.

Either way, I use Mobil 1 Delvac at 5K mile intervals.

Amsoil is reputed to be good stuff, but I really hate their MLM-based marketing program.

Anyway, my local dealer is happy to use oil I supply in the cases where I'm too lazy to crawl under the truck myself.

I hear this a lot but if its bought from the right person MLM does not matter. Beleive me I have plenty of issues with MLM type things but I still do a good business without doing the MLM part of it.

jbplock posted information on the new Mobil 1 Truck & SUV Formula earlier this year. It is reported to be relabeled Mobil Delvac 1. I saw the Truck & SUV Formula at the local WalMart a few weeks ago and plan to use it at the next oil change. Delvac 1 has been tough to find locally.

My preference is Deere 15w-40 +50. It has an API (American Petroleum Institute) rating of CI-4 and is readily available out here in the rural areas......

Some good information at this site on all about oil.

http://motorcycleinfo.calsci.com/Oils1.html

covers most everything and has links to other sites.

I use the Mobil 1 Truck/SUV with the yellow cap. It is Delvac 1 in a different container according to everything I have read. It also has the highest API rating for Diesels with exhaust gas recirculation (all LLY motors).

I to use JD 15 w40 +50 with a JD filter and it costs me about $26. I think it is good stuff and have seen excellent results with it in lots of tractors and other equipment. This is what I am going to use from now on.
