What weight oil is used in a 1980 240D? Straight 30 or a dual weight such as 15w40.</P>

your best option is a multi-weight oil. The 15W-40 weight, regardless of which brand you use returns excellent oil sample results in most engines. A couple brands that are more note worthy of excellent oil samples are the Mobil Delvac and Chevron Supreme 15W-40's.

 

Hi y'all, I've been using 10w30 in my 240D for the last couple years. Should i not be using that weight oil? I haven't noticed it running any differently, i'm just curious if running this oil will damage the engine. Thanks!

 

I am looking at buying a 240D, I have a Dodge with the Cummins that I run Amsoil 15w40 Heavy Duty Diesel &amp; Marine oil in now. If I was to get the 240D I will stay with the Amsoil.</P>


Thanks,</P>

 

John, I agree with your Amsoil recommendations. I've used their products for years. I will say that for less money Delvac and Chevron return excellent oil sample results. It all depends if you want a synthetic or regular dino oil....Can't go wrong with any of them....

 

Remember, ONLY use a C or diesel rated oil and most of the petro oils will be 15W40. The synths come in various weights, but 5W40 would be a good choice. DO NOT use regular gas motor oil (like 10w30) in your diesel.

 

I should know by 12/9 if I am getting the 240D or not.

 

AMSOIL offers preferred customer discounts too. This is the same as dealer cost.

John...Wow, I just noticed your a dealer too. I'm the link on the side bar. How's business
