Which oil?

Ok I have narrowed my choices for oil down even further. The Mobil Drive Clean Plus in 10w-40 or the QS 4x4 Blend in 10w-40. Both these oils are in the $2 a qt range and are available at the ol' Wallyworld here. I plan on about a 4k oci on a 3.0 Nissan (100k) and a 3.5 Isuzu (60k). The Nissan uses no oil and th Zu uses 3/4 - 1 qt per 3k (hoping to end some of this). I have heard/read that the Drive Clean lineup uses a Grp I base oil. Now is this so and is it bad if so? Is th QS blend a Grp III synth added to what Grp base? Which would be the better oil? Sorry for so many questions but this process is quite invigorating for me.

Wow, ~$2 in shelby? Mobil Drive Clean is $1.17 at the wallyworld in raleigh. I've never tried Mobil Drive Clean, but Havoline is rather good, albeit slightly more at $1.27. Look at their VOA. [ May 16, 2004, 12:11 AM: Message edited by: seotaji ]

Seotaji, the regular Drive clean is around a dollar a quart, I was referring to the Drive Clean Plus Blend at $2. The Anti-HDEO crowd is scaring me with the lack of friction modification in the Rotella 5w-40 so I guess that oil is out since I will think about that for 5,000 miles if I use it! Now Syntec has an interesting full synthetic (Grp III) 10w-40 out, is that one worth messing with since it is twice the price of the Drive Clean Plus and QS 4X4 Blend?

DustyJoe, the Nissan is a SOHC (VG30E), the DOHC is the Isuzu 3.5 in the wife's Trooper. Absolutely no problem with the Nissan except that I wish it had about 50 more hp [Big Grin] and I want to use the same oil in both vehicles.

Same one in my old maxima (3.0) Excellent engine. If I may offer suggestion. GTX, Pennzoil or chevron/havoline. In 5w/10w30 Flavors. Just make sure the oil filter you use has an adbv ( my choice was wix)since it points down. That engine will run a long, long time. Long enough for you to replace the governors in the electric windows at least 4 times on all of them. Not sure about the Isuzu, never had one. My OCI for the nissan was 5k mi.

Well here is another thought. I see on here that people mix M1 10w-30 and 15w-50 for some sort of homebrew. Now this might do what I need (thicken up the 30wt). Sooooo, if you run a 3:1 or 4:1 ratio of 10w-30 to 15w-50, what do you get? Has anyone done a VOA on such a blend? A UOA?

Another question: can Syntec 10w-40 go 6,000 in a DOHC application? This motor does not need any help in making sludge and gumming up the works (EGR and PCV as well as rings).
