What oil to use?

[001CUCV]

Sorry of this has been covered before, search didn't bring up anything relating to cucvs for an oil change. Just bought my m1009 a week ago and gonna change the oil. I know it says on the visor of the truck sae 30, but in searching the Internet I found alot of ppl saying 15w 40 for diesels. So what do you guys run? And any certain brands preferred? Thanks, nick

The majority of use use the Shell Rotella T 15w-40 Diesel oil.

Walmart usually has the best price.

Welcome to the site.

Have you downloaded the FREE technical manuals for the truck? Look in the Tech Manual Forum for the CUCV manuals.

The Lube Order will provide all the quanities of fluids required.

Also visit the CUCV Forum and read the Wiki page and the stickies.

WalMart and Tractor Supply have been cheapest around me unless you catch Napa doing a sale. Napa by me is also running a sale till the end of the month if you buy an air filter, you will get a filter free.

Get it from tractor supply in the 5 gallon pale for Rotella 15w40, that seems to be the least expensive way. Just bought some for $74.00 for 5 gallons.

Seems kinda high...Bought 7 each 1 gallon containers of Rotella at Wally World for 13.29 each... Just keep an eye open when going through the stores and pounce on the cheapest one and store it at the house until you need it. Also, 1's are ALOT easier to manouever than 5's...

I picked up my last batch of Rotella from Rural King in Greensburg, IN. It was quite a bit cheaper there vs here in Alabama. It was $9 something a gallon when I picked these up. Sadly, this was all they had in stock.

Delo 15 40 is what I have used in all my 6.2 7.3 and 6.5 engines.

If it's your first ever diesel oil change make sure you fill the oil filter to the top with new oil. Very important to do this to avoid a damaging dry start condition.

I have no clue who told you to do that but if you get caught doing that to a new cummins or cat you will void all your warranty your putting unfiltered oil into your engine

NEW OIL, Like out of the NEW container. I've been servicing diesel engines for 30 yrs and have never heard of that in my life. Granted, New engines have a pre start pressurizing sys so pre filling is not required. Not servicing as per the PM will also void warrantys. Who does that? Give me a friggin break! I love all the self proclaimed experts on here, Thats why I don't post much any more.

$74/5=14.80, not much higher than your paying, besides the wal-mart near me it was $18.50 a gallon and performance was 22.50 a gallon. Tractor supply is the cheapest I have been able to find so far.........near me.

WTF does that have to do with servicing a 6.2? You still don't have a "clue"

I highly recommend filling the oil filter with oil before installing. CUCV's have no warranty anyways. Also, NAPA oil filters are made by WIX. Fairly priced, good stuff. If you ask them to look up what filter you need they will probably tell you a #1061. I would personally suggest you pay $0.10 more for a #1060, which has an anti-drainback valve that I believe helps decrease the time needed to build oil pressure during a cold start by probably 50% (since the oil stays closer) (this is especially obvious in winter here, when it gets VERY cold). Other than the anti-drainback valve, they are the exact same filter. For $0.10, I figure it can't hurt

 

[Skinny]

Shouldn't need an anti drainback valve because it is mounted vertically but always good piece of mind. I will make sure I get the better filter next time.

Not filling a filter is BS, a warm engine with warm oil takes a whopping second to fill. Engines can idle with no oil pressure without being damaged after an oil change. There is enough residual oil film on everything.

If you are buying oil by the 5 gallon pale, you are a freak with too many CUCV's...I like it

I was just passing along info that are shop supervisor had pass down to us from hq with quality control these days I'd rather have the oil filterd before it reached my engine. But hey what do I know I'm just a self proclaimed expert....
