These are the results from a poll done a while back. That poll didn't include Valvoline Premium Blue, so that is most of what the "other" is.

I guess I am the only one using Mobil Delvac 1300. I change my oil and filter about every 7,500 miles. I have used Rotella, but don't care for the burnt oil smell in the cab after an oil change. Delvac does not do that.

 

I did run Rotella-T but now I tried Valvoline 15 W40 and a K&N filter! Lets see!

 

I've used Rotella 15/40 in all my semi engines (1.5 million miles in the last 14 years) so that's what I use in my Dodge Cummins. Besides, I had 9 cases left over when I sold my Mack.

 

Delvac 1300 every 5000 miles and a stratapore filter. Oil is still light colored at that point, but the time interval is about 6 months.

 

Red Line oil in all holes

 

I run the synthetic rotella/ fleetgaurd stratapore filters.. every 3.5- 4.5k changes

 

First 20,000 miles Valvoline Premieum Blue. Then switched to Amsoil 15W-40 changing everty 7500 miles.

 

I only use Rotella T 15W-40 and change it every 5000 (with filter).

 

I run the ol' Rosmella T 15/40 but think im gonna try the Valvaline Premium Blue this time!

 

Any Blackstone reports on the above mentioned oils ????

Cheers!

 

2nd crank case full of Rotella synthetic, have 7500 miles on it and can still read the dipstick marks through it. Anybody have the address where to send the oil for analysis or how to do it? I may just change the filter this time around, it's due right now.

NOTE: never mind the info, I found it in the next oil thread "Different Oil Question"
