Shell's Rotella T Synthetic Blend is available in 10W-40. http://www.shell-lubricants.com/products/pdf/RotellaTSyntheticBlend.pdf

With that much moly they must have used the synthetic blend HP4M. Interesting that the dealer used that instead of the dino GN4.

I forgot to mention that it's stocked at Wal-Mart around here.

The Nissan owner was incorrect, Castrol's 15W-40 is RX Super Heavy Duty. Their GTX comes in 5W-20, 5W-30, 10W-30, 10W-40 and 20W-50. I use the RX 15W-40 in a Volvo 940 (gas) and used it in a VW Jetta Diesel I used to own. I've never had an analysis done (yet anyway) but never had any reason to...

Motorbike, My bike is a 2003 Honda CB750/Nighthawk. The last of the air-cooled in-line fours, I think. The later versions of this engine like mine have a small oil cooler and DOHC. My riding is light to medium duty, mostly touring the back roads of Texas. Very little stop and go, and revs are...

Hey, guys. I hope that some of you Amsoil dealers can give me some advise. I'm thinking of switching to Amsoil 10W-40 in my Honda CB750. I've used Amsoil in my pickup and I believe in their products. But I have some trouble with Amsoil's new recommended OCI for motorcycles. They used to...

Hi, I'm new here. Does anyone have any experience with Rotella T SB 10W-40? I prefer to stick with a 10W-40 for my Honda and would like to find a semi-synthetic. Unfortunately, there aren't many out there. Honda's HP-4 is pretty much out of the question after what I've read here. Two Shell...
