I have a quart of Supreme 7000 10W30 #703 in front of me. It has the starburst and is API Service SM 10W30 Energy Conserving. Outside of the official ratings, it states that it exceeds API sequence test SM and ILSAC GF-4; exceeds Ford, GM, Chrysler, All Foreign manufacturing specs.
Is there a particular spec that you are looking for? If so, I don't see any others on here.

My question was in regards to whether or not they were API certified. IIRC, companies like Amsoil do not pay for their products to be certified. Do I have that right?
I use schaeffers oil and grease products in my cars,trucks,and equipment.The only complaint is there syn.gear oil I used in my 2004 dodge differentials,I had gear chatter to beat the band.I changed back to amsoil severe gear diff.fluid and lost the chatter.Quote:
I am going to Schaeffer oil and gear lubes a try. A old
towboat pilot was very impressed with Schaeffer oils. Those
towboat diesels are running all the time 24-7. Only shut
down for maintenance. Also a river dredg mechanic had a lot
of good to say about Schaeffers. he said it reduced down
time. Its worth a try.
