Shell Rimula (R4) 15W40 for BOTH my gasoline and diesel engines.

 

The gas station mechanics grumble about apocalyptic engine damage as I order them to pour in the Rimula diesel engine oil for my mutivalve gasoline engine. But said Rimula oil is rated CH-4/SL, which well exceeds the rating needs of the gas engine even though it's 30% cheaper. And I am an engineer, immune to marketing and auto suggestion crap that the engine runs smoother with this or that more pricey stuff

 

Baloney - if the oil meets the API engine ratings, and is from a reputable company, use it.

Agree completely. I always look at the API ratings.

 

I use HX5 for my gasoline engines, and R3x for Diesel.
