Do we need an "Oil" sticky
 

I am not familiar with the labeling of motor oils in the US. Here in Canada oils must be labeled with their approved use, designating whether for Gasoline or Diesel engines. To be compatible with diesel usage an oil is labeled with an API service designation of CC, CD up to CJ-4. To be compatible with gas engines oil is labeled with a SD, SF etc designation. These indicate the additive packages present in the oil. Some few oils, usually synthetics, have both designations on them indicating they can be used in either Gas or Diesel engines. In my experience oils with a 40 in the viscosity are likely diesel rated ie 0W-40, 5W-40, 15W-40, though one should still check for the CD etc rating. I raise this issue because many questions to the Forums refer to oils by their viscosity only leading me to believe that there is a lack of clarity about the importance of using a diesel rated oil in their vehicles. The additive characteristics of CD etc rated oils are beneficial to the longevity of the engine and help to deal with the entrained soot which accumulates in our diesel oil. If one is stuck and there is no other choice then by all means top up with a Gasoline rated oil, but the cost of diesel rated oil is usually no more. Given that the organization which administers the ratings is The American Petroleum Institute I am hoping that the labeling requirements system in the US is the same as in Canada. if not that explains the level of confusion. If it says CD, CF, CD-4 - CJ-4 then it is recommended for diesel engines. Anyone else feel free to jump in here if I missed something. Cheers Dan

There are many oils that are "compatible," but if you want the correct oil for a diesel engine, use an oil designed specifically for a diesel engine. These are oils such as the three most common; Chevron Delo 400, Mobil Delvac and Shell Rotella T. These oils have an additive package specifically for a diesel engine. They handle soot dispersal and have a zinc additive necessary for your cam and followers.

Chevron Delo is my favorite with which I have taken several engines to very high mileage. If you're a synthetic fan these are made in synthetics as well. The most common being Mobil Delvac One.

yeah and there needs to be stickies on frequent topics too

This is very true but there's one glaring exception... LOTS of gasoline-only oils are 10W-40. That's the only mainstream violation of your general rule that I'm aware of, but it's a big one. Would hate somebody to get the wrong idea.

anyone here use amsoil european car blend 5w40 i just bought 9quarts for about 80
Any feedback
Its for 99 e300

True & confusing
 

Busted your point is taken , many 10W-40 oils are gasoline only This is why I was questioning if oils sold in the US have the same API service labeling as they do in Canada. Ultimately this is what indicates suitability for use in diesels not the viscosity ratings. Cheers Dan

Putting an oil sticky in here would be like putting a "politics, religion and race sticky" in OD.;)

fellas not quite, AMSOIL 5W40 european car formual is intended for use in gas an ddiesel alike
