Subject: Re: {Chrysler 300} motor oil Do we really think each of theses guys has an oil refinery ? i have a bridge to sell . It is same the stuff in different bottles , why it works the same and so has advocates by brand . None are “ wrong” If you really look at the engineering in oils , Mobil 1 synthetic , or synthetic generally, came out of the severe duty that an airplane gas turbine needs, the difference is all the polymer chains in synthetic are made the same length . Natural oils vary all over the place . Consistent repeatable lubrication is the result . So despite all kinds of rain dance stuff , such as purple dye, Pennsylvania sources etc etc , Mobil 1 is the best oil if you want the best oil . Why it costs so much and is in aircraft engines, where there is extreme stress . It is engineered to be the best , Most of the other stuff is marketing hype. Related, I read a test , might have even been SAE , where they ran a 350 sbc in a Camaro until the oil showed loss of additives etc — for real -still ok but string to decline — not “recommendations “ to change it . Mobil 1 was still perfect at 18000 miles . Others had failed earlier . So we waste oil like crazy changing it all the time for nothing handing the oil co money . It turns black due to detergents holding junk in suspension as it was designed to do . Predictable performance vs temp comes from those engineered polymer chains. A better place to spend money is a real mopar oil filter , many others are junk . The reason it has to be good is modern oil change intervals (Toyota is 10 k? and synthetic ) combined with warrantee . Mopar is not motivated by profit on oil filters but by no warrantee claims on engines due to dirty or inadequate oil or poor filters . I saw the various filters cut open , you would not believe what is in some name brands that come from china now . As in roll of toilet paper . Mopar one was really good . Based on all this I use Mobil one 10-30 for 10 k miles , same $ over 10 k as other ways change filter too . This has coincidentally brought back some pretty sad 150 k mile V8 engines too , it cleans them up . lifters stop ticking etc after 10 k miles Two 4.0 jeep daily drivers since 1997 , one went 320 k other now is at 250 . Both use zero oil over the 10 k . That i cannot believe !! but true . I am sold . I do put zddp in , sort of nothing to lose on that with mechanical lifters Anyway , what one engineer thinks .. Sidebar— I’ve read Rotella, although high zinc, has aggressive additives designed for diesel engines, that can be detrimental to our older engines. Anecdotal bobistheoilguy data but I’m not risking it.

Why do you guys run such thick stuff? 20w, etc? Castro came out with this super cheap high zinc oil as well. (2nd link).

My collection of internal combustion Mopars seem to happy. I too vote for the AMSOIL Z-ROD, high zinc, high phosphorus formulation. Comes in 10W-30, 10W-40 and 20W-50. Right up there with the best. AMSOIL is an American founded, owned and operated company out of Superior, Wisconsin. Yes, but I use AMSOIL "Z-ROD" w/ the Zinc it comes in many viscosity "flavors" from 10W-30 up to 20W-50.

I like Valvoline VR1 “racing oil” as well for the zinc content. It’s a little more expensive but seems to perform well and do what the older motors need. This subject is hotly debated on a Corvette forum I frequent where many participants are engineers and former Big 3 employees. The consensus among them is Rotella 15W40 or its equivalent meets all requirements for mid century high compression sliding surface (flat tappet) engines. Though sold for Diesels it has sufficient zinc and is the most economical. I don't use it. I fall for the allure of oil formulas for old cars. I use Brad Penn 10W40 in everything and have for over 20 years. Did you ever see the pretty green color?

My family has always run Pennzoil in all our old cars but it gets old buying it in cases of 6 quarts if I need to do multiple oil changes. I was considering Rotella T1 as it seems you can buy it in gallon jugs at least. Does anyone have any advice?
