Anyone try this or have feedback ? I always heard that Mobil 1 "wasn't as good as it used to be" because they took out the zinc - or is it "ZDDP" - anyways, not to start another motor oil debate - just wondering what the story is on this oil.

Definately not for you penny pinchers out there - $100 for 6 quarts ! :O

It's about time but the viscosity selection is pretty slim 0W-30 and 0W-50. That zero always worries me in our old engines in the climate I live in.

With our older engine I wouldn't go lower than 5, but have no good reason for saying that.

I used to work for Shell and I think all the major brand oils are good. Shell makes Pennzoil, Quaker State, Crappy Tire oil in Canada and a bunch of others, plus their own Shell brands. Everyone uses the same blend stocks and many come out of the same plant.

Like gas prices, not worth getting obsessed about unless you happen to like getting obsessed.

mobile one oil shrinks oil seals, and causes leaks, redline (ester based) swells seals, and has always had plenty of zddp in all their oils. use redline for synthetic, otherwise use kendall, or if you want boutique non synthetic, use swepco or joe gibbs or brad penn

Can you back this information up?

Can you link to this oil? I've never seen mobile 1 "racing" oil.

Also, on the mobile 1 website, the "regular" oil (0-5-10w20-30-40) have less ZDDP. The 15w50 formula was never changed. It still contains the "old" amount of zinc....because its not an oil recommended by any manufacturer, so its not a commonly used oil.

OMG, I almost fell out of my chair laughing. That is a quote for the signature I think....

porsche and mobil recommend 0w-40 for our cars

Here is the current product data sheet for all Mobil One Engine oils: http://www.mobil.com/usa-english/mot...duct_guide.pdf

Based on the recommended 1200 ppm Phosphorus and Zinc levels for our engines, the best choice appears to be 15W-50 for street use and 0W-50 for racing applications.

Kendall GT1 20w-50 user here! I loved when I worked at O'Reillys. I could get 7 quarts of GT1 for under 20 bucks!

I merely pointed out a commentary by Ryan Stark of Blackstone labs. I did not make any comments on the article. Everyone is free to draw their own conclusions.
