I use NextGen Maxlife in my xj. I've been using it for 3 oil chances now. I would step up and use full synthetic, but I have a slight leak, and I don't feel like paying 7-8$ per quart.
From what I can tell, it holds up fine. It has very slowly started to clean my rockers from what I can (they have a some sludge and gunk on them from PO).
Valvoline's MaxLife is a synthetic blend to begin with, and nextgens version is still a synthetic blend from what I know.
But that's just a personal experience. If anyone can link articles about NextGen, that would be best. Reading is power, and all that.

In regards to the Rotella Zinc post, most high mileage oils such as Mobile 1 HM have zinc in them (zddp is the tech term IIRC). It's on their website.
I used Rotella T6 Full Syn mainly because it was the only 5w40 I could find in the area.

I've used it for the past three changes (3k service intervals) with zero issues. It's cheaper down here in GA than most everything else.
The 4.0L is a pretty tough motor, not to mention its not working very hard; low RPM's, low compression, and dragging a light truck. I see no reason to use "high quality" oils.
Hell, I use Vavoline Diesel (more zinc content & less detergents) 15W-40 in my 500hp boosted 2.0L 4cyl. and v-twin sport bikes and that stuff ~ $13/gal. It's been working well for me for almost 3 years now.

Just seems like the re-refined oil sellers would really be "out on liability limb" if their product didn't live up to it's API rating/certification, no? FWIW, a chemical engineer with XOM told me new motor oil is refined only once......re-refined/re-cycled motor has been refined at least 3 times.....once after it came out of the ground (at a refinery/new motor oil), once as it is being used in a motor (he said that's a refining process) and a 3rd time when it's re-refined/recycled.

rotella oils are clearly marketed for diesel engines.
I know they have less zinc than they used to, but diesel oils have more than oils for gassers

FWIW, straight from mobils website:
http://www.mobiloil.com/usa-english/...gine_Oils.aspx
Question: Presence of Zinc in Engine OilsDoes Mobil Delvac have zinc in the oil? A lot of racers are using Shell to break in their cams in HP engines due to the zinc in the oil. It works the best. I think most oils for non-gas cars have zinc in the oil to help something?-- Jeff Paquette, Raymond, NH
Answer: All engine oils have an additive called ZDDP (Zinc DialkylDithioPhosphate) for wear protection. In general, heavy duty engine oils (truck oils like Mobil Delvac) have a higher level of ZDDP. Automotive engine oils generally have a lower level of ZDDP to protect catalytic systems. For details on phosphorous levels in Mobil 1 motor oils, see a related question and its answer.

I'm looking at a jug of Rotella T6 Syn 5W40 and nowhere does it say "FOR DIESEL ENGINES" or "FOR GASOLINE ENGINES". It does say "API SERVICE CJ-4/SM. which are diesel and gasoline API certifications/ratings.

the entire page is about diesel engines, nothing about gas engines. the whole "DO YOUR DIESEL RIGHT" in huge letter on the top of the page, next to a semi truck sort of hints that too.
it is clearly a diesel engine oil rating

API Service Category CJ-4 describes oils for use in high-speed four-stroke cycle diesel engines designed to meet 2007 model year on-highway exhaust emission standards as well as for previous model years. These oils are compounded for use in all applications with diesel fuels ranging in sulfur content up to 500 ppm (0.05% by weight). However, the use of these oils with greater than 15 ppm (0.0015% by weight) sulfur fuel may impact exhaust aftertreatment system durability and/or oil drain interval.
but you are right, its a gas engine rating too

the images of semis, tractors and trucks, and the listing on various DIESEL engines it meets specifications for kind of gives you that idea as well
