| Any recommendations on oil filters. I have a 300B and want to put a spin on filter instead of the cartridge. I have the adapter but I am having problems narrowing down a filter that will suit what I have.
This conversation is actually quite informative for me as I am getting the car running again and wasn’t sure what to use in terms of oil. My grandfather used 5W-30. Or atleast that’s what was in his breakdown kit. I never saw him actually change the oil.
Any insight is greatly appreciated. On Jun 23, 2023, at 8:34 AM, dplotkin <dplotkin@xxxxxxxxxxxxxxxxxxx> wrote:
John, did you happen to read the white paper I sent last week or maybe earlier this week written by Duke Williams? His analysis is similar to yours although he does not recommend mobile one specifically because he believes the zinc is necessary in sliding surface valve trains.

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.

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

For the engineering types among us is the attached article about oil for vintage Corvettes (whose needs are no different than our Hemi, B & RB mills.)

I also use Brad Penn. Buy a case from Summit Racing and they will ship it free.

Like Danny, I’ve used Brad Penn and ZR1 - both great w/zinc 20/50.
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.
