Shields up!

I almost mentioned this in my reply to Rick Jordon's poll on oil brands, but he asked us to leave out the opinions. So, here I am on a new topic.

Those of you using Mobil 1 oil in your Diesel engines, please check the ratings. That oil is not rated for Diesel engines and Mobil does not recommend it. This was verified when I called the Mobil consumer information line last year.

Mobil makes two oils that are recommended for our Diesels - Delvac and Delvac 1. The regular Delvac is ordinary dino oil and would be comparable to Chevron Delo or Shell Rotella. The Delvac 1 is a full synthetic that I would use if I could find it. In some parts of the country it is very rare and very expensive at $6 to $8 per quart.

If you're having someone else, such as an MB dealer, do your oil changes, you might want to check on what they're putting in your engine. Just two weeks ago, my dealer put in Castrol GTX 10W-40 in my engine, and that oil is not Diesel rated. I've also heard of several other dealers putting the wrong oil in Diesel engines. So don't just assume that they know what they're doing!
