I'm a big fan of Redline oils generally, but I think there are 0w40's that are as good available at less cost. For instance, given a choice between RL 0w40 and M1 0w40, I would go with the M1.

But for a diesel, I would go with RL 5w40. No second thought about it.


For a truck requiring API specs, sure, RL 5w40.

For those with pax diesels, there's Euro specs for that.

I was thinking that since you have your Jetta modified, you might be running high fueling rates and could be loading the oil with higher than normal levels of soot. A real heavy-duty oil would be good for dealing with that kind of a situation.

I follow ya now. It's modified well and doesn't soot.

Previous UOAs have showed small to no amounts of fuel and low soot/insoluble levels.
