Schaeffer Manufacturing Co. 0700CK4-012 SynShield Durability Advantage 15W-40 Diesel Engine Oil, 12-Quart Bottle (Pack of 12)

Use this oil in my 2010 Chevrolet diesel and change my oil every 10,000 miles. Great oil

Great oil, can go way longer now on oil changes. Saves money on maintance. And motor runs so smooth.

Dont buy

For Hubbys stuff..

I run this in my 2015 F250 6.7. They actually sent the correct oil this time. Change oil and filter every 5k miles.

Great oil

Top of the line oil no doubt but, it’s advertised as 5 gallons but only contained 4.5 gallons. Where are the other 2qts I paid for?

I can’t say enough about this Diesel engine oil. Best stuff on the market.

Swapped to schaeffers from Rotella 15w40 and noticed increased oil pressure, slightly better fuel economy, and a quite engine. I was quite impressed. Its really good oil, but... the downside is the price, I recommend going through a nearby sales rep as the prices are exponentially cheaper than buying from a 3rd party vendor such as Amazon, Napa, O Reillys etc.

Great fuel economy, incredible oil!
