Sidebar question, how much do I need to add? Is it X amt per so many gallons of diesel??

No Sir, we have a misunderstanding here, It's not a requirement to add 2 cycle engine oil to your fuel.

Its something some do for peace of mind and it dose add lubrication quality to the fuel you are using, the same with ATF.

But I would say if you never use an additive to increase the lubrication quality of your fuel, you may never notice the difference.

We really don't put enough mileage per year on our coaches to notice a benefit, as where an OTR trucker would.

The newer fuels produced today are better than what we got when we first started using low sulfur producing fuels.

I'm sure if we wanted to review some of the fuel formulas here on this forum, there are some active or retired petroleum engineers with us.
