What weight non- synthetic oil should I use in my '94 C280 ?

Thanks...

 

Need more info. Like where do you live and what tempatures is your car exposed to. Although, I will say that Mercedes calls for 0w-40. I have been told by a local mercedes doctor that you don't want to go higher than 5w-40. Because the tolerances are so small. However, there are other people that simply adhere to the tempature school of thought.

 

I live in eastern Pennsylvania and my C280 is a six cylinder.

 

Well I would check the Mobil's website to see what weight they reccomend for your tempature. But don't ever move down weight in oil. Also if you have a V6 it holds 8.5 quarts of oil.

 

c280 wizard should chip in here, he knows far to much about oil <
but i run 10w-40 shell syntech i think it was called, i live in New zealand moderate climate.
you could probebly run a high quality fully sethentic in your car and extend the oil change interval

 

I wonder if MB recommends different weight oil for the straight 6 and the V-6?
I have the V-6 and I know that MB dealers will recommend 0w-40 Synthetic.
My local mech recommends 5w-30 in the C-Class, but I told him to go with 0w-40 untill I checked around.
The thing is, a lot wrench heads I've talked with say to keep the low and high numbers as close a possible. In other words , the more multi-visc your oil, the worse it protects you engine. I'm not exactly sure if this caveat applies to synthetic oil.
BTW, I live on the West Coast and it rarely gets below freezing in the winter. I prob don't need the 0w oil, but then I feel it starts to lubricate more quickly at start up, so I use it.
