That's why they're up to T5 (or 6) now. T2 straight weight is still the spec it originally came in. It's actually specified for stationary diesel power plants, not vehicles.
I verified the the zinc level with the shell distributor before I decided to use it.

Day one did not go well.
These were two of my Dellorto venturies.
