Diesel Engine Oil

Code54 · Jul 30, 2013

Some very interesting points and thoughts - I do like how Cummins don't sell the oil but tell you to use the approved oil which is valvoline - can get it a million places and at a decent deal. Thanks for the information and I will keep reading and learning!

What I plan to do for my 1025 (with Yanmar engine) is to buy 3 quarts of Castrol Edge at my VW dealer for when I change the 1025's oil. They sell it for $8/qt, which is less than Mobil 1 ESP, and I cannot find any Mobil 1 ESP except on line for nearly $13/qt. Castrol Edge is 5W30. This matches the chart requirement in the owner's manual. Wish I could get 0w30, but they don't formulate it to meet VW's 507 spec.

The only difference between a 0w30 and 5w30 is that the viscous is less at starting, or lower temperature, on the 0w30 but it's the same as running temperature.

Hi Ralph - the Castrol Edge 5W30 that I'm familiar with is an SN spec gasoline oil. Is that what your Yanmar calls for ?

No, the VW 507 spec is for diesel, with additives to deal with the exhaust filtration in the 2009+ models. The oil container is labeled ESP for exhaust system protection.

It didn't sound like the right oil to me, just wanted Ralph to double check.

Nope - Yanmar calls for 15W-40 or 10W-30 API CG. Have new JD 1026R. Do NOT use an automotive (API "S" class) engine oil in a diesel engine!! It does not have anywhere near enough dispersant additive to hold diesel soot blowby in suspension, and will plate-out and cause valve train wear.

Came across some LiquiMoly today in a Napa. 5W40 Diesel. Not cheap. I'm going to research it further, but mentioning it now for the poster that was looking for older spec oil - this LiquiMoly is CF rated.

IE. not suitable for new emission diesels, but may suit for an old application. Rgds, D.

The 5w30 Castrol Edge is for the VW TDI clean diesels.

According to the charts in my 1025 owner's manual (and same in the 4010 manual), a xw30 oil is fine unless you live in very hot parts of the country, like Arizona, New Mexico and southern parts of Texas. It's certainly fine in a VW TDI.

German castrol as it is called is one of the thickest 5 w30 on the market. At the top end of both ratings.
