Wrong Oil? What you running?
I was looking at the Amsoil Site last spring and read they sell a 10W-40 synthetic oil for stationary engines that contains no viscosity indexer. The stuff just comes from the plant that way. So, I contacted the Amsoil Guy who frequents the oil threads and said why don't you package that for cars. He said he would see what he could do.
Nothing since but still hoping.

Myself and a few shops that have built serious evo's go with 20/50. primarily because I drive mine hard and most people do.
dont use mobil 1 at all they used to be top of the line but with new standards in the industry they have changed their formula. I used to be in the oil industry and had a mobil rep tell me to go else where.

Slightly true (ie they changed 10w-30 & 5w-30). BUT, Mobil 1 is still a great choice for an over the counter oil. If you haven't read the last couple pages... Half the people on this forum dont need "20/50".

okay well if you use mobil 1 10w30 like most of us here do and WANT THAT HIGH ZINC, use the high mileage one instead of normal, it has over 1000 zinc/phosphorus count compared to the normal mobil 1 which is like 800. both at wally world for $25.
Good Stuff man
Here's the chart for Mobil 1 oils, maybe I'll try their 15w50, it've seen it at wally world for $25 as well and it has the highest zinc content of them all. http://www.mobiloil.com/USA-English/...duct_Guide.pdf
Stay away from standard synthetic mobile 1. I had a factory MR turbo fail at 90k miles because of that crap. Good oil is Amsoil or royal purple in 10w30 if temp does not go below 35-40 degrees. If running higher boost levels or moderate mods, you can bump to 20w50, but I say stick with 10w30. Forced performance has a great article on their website discussing recommended oil

I will agree there are better oils then mobil 1 which isn't a full syn but for a stock car thats not pushed perfectly fine. I run royal purple 10w30 and change every 2500 miles, but I also push my car regularly and run much higher then factory boost.

Actually, Mobil 1 is not synthetic at all. Refiners had finally achieved the technology to extract the same oil as synthetic from mineral oil and it was cheaper to do so. So, they sold it packaged as synthetic oil. Talk about a money making deal. Not so fast said the lawyers – you can't be calling this synthetic oil. Well, the judge wasn't convinced, he ruled anything that is the same can go by the same name.
Same here, I live in AK but I run 5W-30 all year round and have no issues. 20W-50 seems absurd.
I think in the service manual there is a list of different oil weights for temp ranges and how hard you drive... I think

Not true. High mileage has less than 1000 ppm of ZDDP. More like 900ppm, according to VOA's posted on BITOG.. But all in all, its definitely a great oil and even better choice than the traditional 5w-30 mobil for sure. Again, the Mobil 1 oil that has the highest ZDDP is 0w-40, of course excluding the V-twin formulas and their racing formulas (15w-50)..
