Reply to "DEXOS VS GF-5 LUBE STANDARD"

When I bought my Titan from auction, it had been serviced, with bulk oil, presumably dino. I ran that for about 3K and it was fine. I changed to Mobil-1 10w-30 and ran for 7500 miles. I did notice more valve train noise (others have posted similar stories with M-1). I was given several cases and jugs of Pennzoil Platinum 5w-30 and am using it now. The valve train is quieter and for some reason, the coolant temp gauge reads slightly cooler. Nissan specs 5w-30, 10w-30, and 10w-40 weight oils. The thicker for above 32 degrees. The 5w seems fine. I will use the Platinum until my stash runs out. I am still considering using conventional later on.

Since I do tow, I added a larger oil cooler and a larger pusher fan (manual switch) about a month ago. Used to hold about 6 1/2 quarts, now almost 8 with filter.
