Im due for a oil change. Im going to give the Rotella Syn a shot this time. I'll continue to use it. I've got about 15,000 on this fuel filter also. Time for it to go!
I would be suprised if anyone has heard of it, but I use Brad Penn oil. They are out of Pennsylvania. I can get a 5 gal. bucket for $41 delivered. I have had great luck with their 2-stroke oil in my sled and also their 15/40 in my truck.
That reminds me, it's about change time. I'm trying to hold out and do my trans spin on, fuel filter, and oil change when my nicktane gets here. Install it the same day that is, and finally get a good baseline reading for my kennedy restriction/psi gauge. I realy wana see if the nicktane will drop my pressure any.
Rotella on the LB7 for the last 92k Also Rotella for the LLY but I have only changed it once since I have owned it. I was thinking about changing the LLY over to ROYAL PURPLE because I run it harder then the LB7 but when I went to buy it was like 7 or 8 bucks a qrt. I like to change my oil & filter every 5k or so. 8 bucks a qrt every 5k would ad quick so I stuck with the Rottela.
