Rotella T1 30W or Supertech HD-30 for Small Engines

[z71bill]

I can't really say that either one is better than the other, the Supertech likely uses a modern PCMO add package while the Rotella T1 is an older lower ash package for Detroit Diesels, in OPE engines changed at a reasonable interval there'll likely be no noticeable difference between either, although one may find quart bottles a more convenient for filling small engines over a gallon jug.

SuperTech quart bottles have a big wide mouth hard to pour without a funnel.

I have a 2 gallon jug of SuperTech 15w40 I bought on sale for $20 I will have to transfer it into smaller containers.

If the engine is a side valve,use Briggs SAE 30.Your engine will last longer than on any other oil,and change it once a year,if you remember.All the ohv engines run just fine on a quality 10w30.Dont sweat it.

Give your OPE the leftovers from your vehicle’s oil changes.

I use a 0w40 in all of my air cooled OPE. It definitely makes it easier since I use it in a few of our vehicles with 5+ quart sumps.
