I was reading a TDR article on oil. It stated that 15W40, Vavolin Premium Blue was a good product and that it was available in Synthetic and convential. I have checked a couple of places and can not find the convential.
1. What are your thoughts on the oil?
2. Where do you get yours?

 

Endorsed by Cummins, great additive pack. NEver heard of anything wrong with it.
When I buy I get it at my local Cummins dealer.

 

your correct! PB is one of thebest oils you can put in your cummins. you probably saw the PB extreme 5/40. THats the Synthetic version. They no longer make the Premium Blue 15/40 Convention in a CI4+ ONE GALLON JUG. The PB CJ rated stuff is readily available in most stores. You can get the old CLASSIC BLUE in 5 gallon containers ( It is CI4+) just not in CALIF!!! LOL I have been running the PB CJ stuff with GREAT results as proven by UOA's. I am not afraid of the CJ stuff anymore!

 

I can still get the CI+4 here in Texas at Car Quest stores and some Advanced Auto Parts stores. It is not toally gone. Harder and harder to find though since the change to CJ

 

Is everyone using 15w40, 10w40, 5w30?
Is the only difference the temp range?

 

Its the only thing ill run in my truck........i work for cummins and thats the only oil we use, so i figured it was good enough for my truck.

 

I've been using the PB when I bought the truck, and PBE synthetic after the engine broke in. I change it every 15,000. I'm a couple thousand from the next change, and will send in another sample. It's good oil in my opinion. I buy mine at CarQuest.

 

Flying J still carries the 1 gallon jugs.

 

Flying J sometimes has a deal on the Valvoline. Have to watch their website.
Autozone has it for right at $13 a gallon here in Virginia. Motor oil prices will be increasing soon. I read in the Lube reports. Bad news everywhere.

 

It is Valvoline, does any more need to be said. Valvoline is the only oil I have ever ran for the past fifty years in all my Drag cars, Top Fuel Dragsters. motorcycles, cars, trucks, and lawn mowers. I have never had a oil related failure.

 

I get it at NAPA. One of my son's hot shot drivers has a secondary Amsoil filter and after 60K miles his oil tested better than Amsoil at 30K miles. He will never go back to Amsoil. PB is all I use. Due to economics I blend two PB with one PB extreme.

So is everyone using 15W40?

 

I use the Premium Blue Extreme, it's 5W-40 synthetic.

If you use the Premium Blue, it's 15W-40.

 

I just clicked on the link and I see they changed the packaging for the Premium blue! Kind of cool!

 

PB is good oil,but not neccesarily any better than Delo,Delvac,or Rotella.

The Cummins is known to be easy on oil,it really doesn't matter what you run within reason.
