FYI Mobil 1 Synthetic 0w30 5 quart for $10

Nice score. However, I don't think the formulation of Ultra that's sold now (SN, IIRK) has the super low NOACK of the old (SM) formulation. UB can shed a bit more light on this.

I was off by a few tenths. http://www.svtperformance.com/forums/showthread.php?996171-Pennzoil-Platium-PurePlus/page2

Pennzoil Ultra Platinum 10W-30 shows a 5.7% NOACK. Since SAE 10W-30 grades seem to have the lowest NOACK (most of the time), this is your benchmark for the newer formulations.

I do not understand how Ultra Platinum 5W-30 has a 6% increase in NOACK (total of 11.5%). That's unheard of.

Even the new 5W-20 formulation specs above 10%. SMH!

Even though Pennzoil uses the GTL process, GTL base oils alone are not viscous enough for use in a passenger car engine. Therefore, more viscous base oils must be blended with them. What they are using for a blend must be where the impurities come from, resulting in higher NOACK. This does not explain their 10W-30 formulation, as it seems to be on par with what I expect from a top tier lubricant.

So, if Ultra Platinum 10W-30 can be easily found on the shelf, it's my new "go to" off the shelf lubricant. Wal Mart currently only lists 5W-20 and 5W-30 (available in stores only), so we shall see. Next time anyone is at your local Wal Mart, look to see if 10W-30 is in stock. That's going to be the winner for UOA testing.

Ok, some updates on this clearance sale!

Castrol edge 5w-50 Quarts to $2.00

I ended up buying 30 quarts of Castrol edge 5-50 for $60, and turned around and sold 12 quarts on Craigslist for $50, so I'm into 18 quarts for $10, two oil changes on the boss 302.

Nice! I could do that, or not have to buy oil until I'm in my mid 30's lol.
