What customers say about "Key Specs"
Valvoline Premium Blue 15W-40 Diesel Engine Oil
  • I have a Ford 7.3 diesel with 200,000 miles on it. Previously I used Amsoil synthetic and my truck used a quart of oil every 1,500 miles. After switching to Valvoline Blue oil consumption dropped by a considerable margin, to almost none.
  • It is what it is great oil for a good price for my motor home. If your out on the road and need oil you can find it everywhere not like some of the specialty brands of oil
  • My father introduced me to Valvoline long ago it is the only brand oil I use along with the onther thing he would say "with Oil change it early & use a good filter.
  • I have a Ford 7.3 diesel with 200,000 miles on it. Previously I used Amsoil synthetic and my truck used a quart of oil every 1,500 miles. After switching to Valvoline Blue oil consumption dropped by a considerable margin, to almost none.
  • Valvoline is the best. WalMart has it for $11.99 (3-14-16) for a gallon (new white bottle). My truck takes 16 quarts (4 gallons) so price is a make or break issue.
Shell Rotella T6 5W-40 Full Synthetic CJ-4/SM
  • This Shell Rotella T6 5w-40 Synthetic engine oil is both a quality product and very affordable for 4-stroke motorcycles which use 10w-40 conventional engine oil.
  • I run this oil in a 1994 Ninja ZX6E, 2012 KLX250S. Both run flawless. It provides amazing wet clutch shifting.
  • My ZX6E when I bought it had Mobil 1 10W-40 in it before and my 2nd gear often slipped a lot. I was worried big time I bought a junker. Swapped out the oil with some Rotella and well 2 years later that slipping never occured again
  • This oil completely stopped the cold start surging on my 2000 7.3 Powerstroke F350, even at below zero without being plugged in...
  • This oil does exactely what its supposed to do! Engine is quieter, runs smoother, and stays cooler.

What customers say about "Features"
Valvoline Premium Blue 15W-40 Diesel Engine Oil
  • Cummins approved for my 2013 RAM. Meets the new MS 20087 spec.
  • Use it in my 2008 Dodge Ram 2500 Diesel. Works great!
  • Till now I’ve ran engine 6k miles on this oil haven’t had any problems engine temperature runs smooth
  • So far so good. Used in my 2015 Ram 2500. Will update when I change the oil next time.
  • Convient & what I wanted. Additives already added to the oil for less wear on high mileage vehicles.
Shell Rotella T6 5W-40 Full Synthetic CJ-4/SM
  • Rotella T-6 is a sleeper in the motorcycle world. I have run it in an XR250 dirt bike off road (which is a serious test of how it works in a wet clutch.), a Honda VFR800 sport bike and a Honda Shadow cruiser. Zero problems or issues of any kind.
  • Blackstone lab analysis showed a very good additive package and essentially zero wear after a hard run in the sport bike. This oil is JASO MA rated for wet clutches. The price is a bargain relative to "motorcycle oils". Being a 5W-40 this oil starts easier in cold weather than petro oils.
  • I have been using it in my Kawasaki Vulcan 900 Classic LT for some time with zero oil consumption, and on my oil pressure gauge it registers according to the Kawasaki shop manual spec regarding pressure.
  • Just bought a 2002 Kawasaki Concours motorcycle and the previous owner swears by this oil. Did some extensive research and online Concours forums questioning, this is THE stuff for improved cold starts, better shifting, and overall performance.
  • I have a bandit 1200 GSF Runs excellent with this oil with my wet clutch and its rated Jaso Ma. Great price.
  • This is an excellent product. I only took 1 star off; as I'm not sure why Shell is the only company that sells 4 quart (1 gallon) jugs. Most vehicles take between 4-5 quarts.
