ive used only purolator.. my oil burning is normally good.. 3/4 to 1 quart every 3k miles.. although the last 3 weeks or so its burning more.. probably time to change it again
I use Deutsch PV 193. It seems ok but you are right. It is not a snug fit.
I will try the Purolator PV 1061 next oil change
I need to find out what valve I have been getting from Napa. But I usually go through less than a quart of Royal Purple every 3K to 5K. I rarely check the oil nowadays actually - I should probably pay more attention though. I pour Sea Foam through the PCV port, the oil fill hole, and in the fuel tank a week before an oil change to loosen all the accumulated gunk before I change the oil to get things as clean as possible for the new stuff. I even jack up one side of the VX to get more old oil out. I use Royal Purple followed by a quart of Marvel Mystery Oil in the motor at every oil change. I also use Royal Purple in the trans, t-case, and diffs - and, no, I am not a salesman!![]()

I didn't retain my LSD when I swapped in the 4.77's - not sure I could have. So no additive needed in my diff. I forgot what I used when I did have the LSD though.
http://www.marvelmysteryoil.com/main.taf?p=1 I love this stuff! If stuck rings are the oiling issue with your 3.5, it might be worth it to get the spray bottle to shoot down the cylinders through the spark plug hole, let it sit awhile, crank the engine, spray some more, let it sit for a day, put the plugs back in, run it for a while, then change the oil and add a quart of MMO. Besides, it is a good idea to inspect the plugs if you are burning oil as they may be fouling.
Yeah, I need to figure out what the best LSD additive is and how much to put in.
Hmmm, interesting. My plugs were changed about a year ago, so I doubt there is any fouling by now, but you never know. Hopefully the Purolator valve will show some improvement. I will probably do another SeaFoam treatment next time I change the oil also....
Thanks - Bart
Purolator is all I've ever used...new one at every oil change. So far, 0177 uses no oil between changes. K&N filters, Mobil 1, and a long, easy break-in didn't hurt (it took 20 months to put on the first 2000mi....I've other DDs and the M-coupe toy...only bought it cause I really liked the way it looked)
