Some head-to-head comparisons...

Per the 4-ball wear testing, and Marc Haibeck's recommendations, my choice has been the Amsoil 10W-40 full synthetic. I've NO chain rattle after the first couple seconds after the engine starts. Once oil pressure is up, there's no rattle...ever, consumption is typical for a 90 LT5 with seals installed on all valves (modification via Marc Haibeck).

I use 15W-40 CASTROL GTX Diesel on my LT-5. I like the thicker oil. Has sufficient zinc in it also.

XfireZ51, yes the Vibe/Matrix line has been very reliable to say the least. Our Vibe needed a intake manifold gasket a few years ago, and this year needed, a RR wheel bearing, a RF brake caliper & new front pads. It will need a complete rear brake rebuild (new drums, brakes, hardware, etc.) as it still has the original items back there, the rear brakes have not had any replacement parts in all of these years and with all of the mileage. So I can not complain at all, for this vehicle doesn't owe me a penny. A side note, I still say that the micro-fiber seats in our Vibe are still one of the most comfortable seats ever put in a car.....JMO........
Besides batteries, front brake work, and tires, that is it......

Paul, thanks for the good reading material, will have to read it a few times to absorb all of the info. Will probably try the Amsoil next time around. As for now, I am very happy with no chain rattle. I also used the Bosch oil filter I had in stock. I still have a K&N filter to use before going back to the AC DELCO unit.
