Going to buy some oil today for oil change.What should I buy with
only these two choices.

1. Chevron Delo 400

2. Valvolene Premium Blue

 

Why only these two choices? I vote Rotella!

 

i would decide on price. and by the way, chevron is the inventor, and owns the rights to the process by which group 3 synthetics are made.

 

I was told be a diesel mechanic to only use Rotella.

 

I'm with smokingdog, both are good go with price.

 

Advance Auto Parts had Valvoline PB on sale for $1 off in our area this week.

I use the Valvoline 'cuz that's what Cummins uses from the factory.

 

I'm a Rotella fan!

 

I use Red Line 15w40 and have from 30,000 km to now at 197,000 km, I have made over 400 rwhp since 10,000 km, had the head off, internals look great in fact it looked like new. Valve guides good and and doesn't burn a drop of oil. I drop the oil every 15,000 km and replace oil filter every 5000 km.
There are many excellent oils available but as for myself I'll stick to Red Line.

 

DELLO 400 Is the only way to fly.

 

Either one will be fine, I second (or third) the motion to go with price.

 

I have used Rotella T forever with excellent results and my local Cummins dealer sells 20 L pails for the best price around - big savings over 1 gallon jugs.

 

I'm a fan of Redline, but not the $30/gal price.

I now run the Redline 10w-30-- faster spoolup, better mpg.

I don't need no stinkin 40wt oil

Oh-- I also like the new Rotella 10w-30. The specs are almost as good as most synthetics, and cost is much lower.

Pour point is -40!! DINO OIL!!! Diesel Rated!

I thought cummins reccommends premium blue? At least that's what is says on the jug. I always fihured if it's good enough for them it good for me.

 

Rotella is all that I put in my rig....
