Shell Rotella 550046251 T6 Full Synthetic Multi-Vehicle 5W-30 Diesel Engine Oil (1-Gallon, Single Pack)

Why did you pick this product vs others?:It just works

This is the only oil i trust to use in my duramax. Amazon definitely has it for the best price, came in with extra “non spill” sticker tabs so theirs no leaking. Longest lasting oil out there!! I Strongly recommend this oil!!

Been running Rotella for years, sometimes hard to find local so easy and affordable just to have it shipped

I use this oil in my turbo-charged miata. It's a full synthetic oil designed for diesel engines (turbo diesels). The turbo is several years old now, but is still spooling just fine, without shaft play, which is nice. I keep the oil on a 3-5kmi rotation, or whenever the oil starts to turn black. Overall I'm pretty satisfied with it. I don't see any metal particles in the oil when changing it, and the drain plug magnet might have a tiny amount of filings. All pretty normal.I might update this review with some pictures on my next oil change.

great price, long delivery time. wish it had the matching quart(s)

Since I get an email every other day from Amazon harassing me to review this, I am reviewing it. It’s well known as good diesel oil. But no one would actually know how good it is unless they ran their engine 150,000 miles changing this every 5000, and then tore the engine down and looked at the parts under a microscope. So it’s oil. Ford diesel engine. Yay!

used in my 2002 tdi for years now, only oil i use

Great oil, pleased with the quality
