Possibly the best oil you can purchase
There's not enough time in the day to explain used oil analyses or what the 5W and 40 mean. I can tell you that this has higher anti-wear additives than all the other oils you've been using. It even rejuvenates seals. I use this over "High Mileage" motor oil all the time. This rejuvenates my seals, reduces consumption, takes a BEATING, lasts a very long time, is always priced extremely well, made by Shell (whom also makes Pennzoil) and yeah.. I've ran this in cars for decades. It's worth trying. Research UOAs and see for yourself. I've seen better wear results from this than Mobil1, Pennzoil Platinum, etc. I won't name every brand, but it's got more additives because it's not pressured to keep the cats clean. News flash, if your cats are failing, it's not the oil's fault lol.

I stand behind this product!
Highly recommend! Paid with a DOCs filter set and your fleet will run like a dream! Less down time, fewer changes and provides that few extra miles of run time if needed without fear of damage or performance loss. I stand behind this product!

Best diesel oil
Only oil I run in diesels. Works great in wet clutch small engines like atvs and four wheelers since it meets Jaso requirements. And use it in my Beamer. Better protection and I swear lasts longer and burns oil less.

this is the stuff for diesel engines
This is the only oil I will use in any of my diesel engines. It's full synthetic, and it's top-tier oil. Scrimping on oil is a very bad idea. If a few extra bucks on oil extends the life of your engine, it is well worth it.

Works Well in My Diesel Truck
Good oil for a diesel truck. The engine runs smoother and quieter after the oil change, and cold starts are better. It feels reliable for regular and heavy-duty use. The only minor downside is that the oil container is a bit bulky and not the most convenient to pour without a funnel.
