NEW to CRD - What oils to use

euromade · **Posted:** Tue Jul 31, 2007 9:02 am

I own a TDI but now that I got a CRD I'd like to know what motor oil(s) should I use?
Thanks a lot!
P.S. Any CRD owners in W. Michigan? :?:

0W40 or 5W40 of any high-grade full synthetic should be fine. You'll find a lot of users on the board that use either Mobil1 or Rotella-T full synthetics. If you're into boutique products (which arguably are a bit better in lab testing), then Amsoil is probably the way to go. I use Rotella-T 5W40 currently as it's nearly as cheap as organic at Wallymart.

Rotella-T 5W40 Synthetic

I tried the Amsoil 5W-30 Series 3000 HD and it worked fine...but now I am happier with the (AME) Amsoil 15W-40 Heavy Duty Diesel & Marine. It has a very high TBN (Total Base Number) to fight Acidity and gives the 40W protection the parts need. Look in SIG below for Amsoil Oil and Air Filter part numbers.

Basically, whatever your TDI is happy with should keep the CRD happy as well.

Other than viscosity grade, just make sure it's a diesel rated oil, API rating of CI-4 or CI-4+ preferably.

As far as brand - your money, your vehicle, your choice.

I am new to the CRD as well. I have been using regular diesel oil with my old Mercedes, as I change the oil at 3000 miles, and synthetic would make the old thing leak more. I haven't even got an owners manual yet, but I will be changing the oil in the CRD this weekend (and sending in a sample for analysis). What is the change interval people use with the synthetic, and is that longer than the interval with regular diesel enine oil?

every 6k miles. You could go more if you do REALLY light load driving and don't ever tow anything, but the cost is minimal once or twice a year.

I ran the 5W30 for 4600 miles and got a UOA...was still very good...a little Aluminum from breaking in...ran it another 2500 miles and switched to 15W-40. I plan on another UOA at 5,000 miles and taking it to at least 7,500 depending on results. I will probably go to 10,000 since the first UOA was so good.

Use ANY synthetic oil that meets the CRD specs and change at 6k. You will be fine.

how much oil goes in? 6.5Q?

and what are the part numbers to the napa gold filter? and any other filters?

It takes 6.4 quarts.

The manual shows a 6,000 or a 12,000 mile service interval. Per the manual only 5-40w or 0-40w synthetic is allowed. Conventional oil is not allowed.

Of course, that is just what the manual says, others here do what they feel is right. Deviating from the manual may result in no warranty, however.

You probably do have a manual in the vehicle-- it is not in the bottom of the glove box, it is right above the glove box in a canvas pouch. Open the box and don't look in the box that opens but look above it and you will see the little cubby hole it sits in.

Thanks for your ideas...purchased 8 qts of CASTROL 5w40 Synt. It was on sale for $4/qt.
Now I have to get it done...
Thanks...
Any CRD owners in West Michigan?

I'm not a huge rotella fan but I just changed mine for the first time with rotella 5w 40 synthetic. Since the CRD has a EGR I will be changing it every 3,000 or a little over just to keep it clean. I did notice at Wal-mart the Mobil 5w 40 syn. was $6.00 higher than the rotella per gallon. I'm sure the rotella will be just fine just because everyone uses it in their farm equipment and vehicles around here. I plan on having the rotella tested at my first 3,000 change. just my .02

I just buck up and get 5W40 Delvac 1.

I use Shell Rotella T 5W-40, the engine runs much smoother with that oil as compared to whatever Mopar oil the stealership uses. In my area stores it costs half the price of Mobil 1 TDT 5W-40 (as well as Amsoil products) and I don't feel like giving any more money to ExxonMobil than I have to (although Shell is #2 as far as oil companies so you'll lose either way).

Run the 5-40 AmsOil European Syn both in my TDI and CRD. 10k miles between changes on both.
And I have nothing in my turbo hoses, have not had anything since day 1. Must have got a good one
as oil alone probably can't be only reason. EHM also helps with previous TDI experience that mod happened
first night.

Isn't the Amsoil AME 15W-40 a little heavy for the CRD?
I just got some for the Powerstroke, but waiting what you hear what you have to say.

In a word... No. A true synthetic's basestock is the high number, 40. The oil must flow in winter (hence the "w") to a certain temp, that is where the 15 comes in.

That being said. A 15w40 class 4 synthetic such as Amsoil, Royal Purple, etc will actually flow quite well down to -45F and in essence out perform a typical 5w40. This is due to the molecular structure of the class 4 synthetic.

In relation to a convential oil that is typically a lower viscosity than the high number and uses viscosity improvers to reach a "40" number, a synthetic will start with a "40" that has the molecular characteristics to flow at lower temps.

In a nutshell, a 15w40 will work just fine in the CRD, that is, if it is a high quality synthetic. The flow characteristics are well within the parameters of a lower quality 5w40.

Just remember... the lower number of any oil is the winter characteristics and NOT the viscosity characteristics of the oil in operation. Unless you are in extremely cold temps (below -30F) consistently, you should experience no problems with a high quality 15w40 synthetic.

Oh.... there is a good 10w40 that amsoil has that has a 12+TBN. It is primarily listed as an oil for gas engines, but it meets diesel CI-4+ specs and will flow to -43F. It is the AMO 10w40 in their product list. Just in case you want to split the difference between a 5w40 and a 15w40.

Man... don't you just love having so many choices!
