which oil do I want

[jonesy]

Rottella T 15-40 not energy conserving, is that what I want. is that a blue bottle or white one. I sort of remember using that last time. A little help, please

[Squidley]

Shell Rotella T is the one, I run it in my bikes. I dont know that there is more than one, just as long as it's the energy conserving your cool

White bottle is conventional 15W40 oil.

 

Blue bottle is synthetic 5W40 oil.

 

Either one is good.
