    Sorry, I messed up with the poll option on the last post, here goes:

    The last poll about favorite oil filters got me to thinking what is everyone's favorite motor oil and why? Do you put different oil in different engine types?

    #1 Valvoline
    #2 Castrol
    #3 Quaker State
    #4 Royal Purple
    #5 Mobil
    #6 Penzoil
    #7 Other

    Mobil 1 has been a staple in my garage, NOLY once a fresh motor is broken in with Valvoline Racing oil or 15W40 Shell Rotella T.

    I voted for other as in Shell Rotella. I used to use Valvoline but since they have taken the zinc and other additives out of all the other motor oils I have switched to Rotella. I have heard that they are going to also remove it from the Rotella as well, so I will then probably go back to Valvoline and use an additive.

      Walmart. No, seriuosly. After they came out with the CI-4 rating for diesel oil, which removed a good portion of the zinc, I began to find it difficult to find Rotella T with the old CJ-4 rating. For awhile, stores carried both, but slowly phased out the better (older) of the two. The writers of the Turbo Diesel Register were curious as to the differences between all of the available oils as they all claimed to be superior. What they did was send 15 or so samples of different oils out to be analyzed, but did not name them, so the person doing the final analysis could not slant the test in any way, due to personal preference. Interestingly enough, some of the cheaper oils fared better than the perceived better oils. In the case of the Walmart oil, whoever it is that makes the oil for them, did not switch to the newer formulation, therefore it has a higher zinc content than those (Rotella T, Penzoil, Delo etc.) that did. So yes, I use Walmart diesel oil in my vehicles and quick hide the jugs after an oil change lest any of my friends see them in the trash. :mob:

      I've used Pennzoil for years with good results, but now that they have gone with the new API rating of SM which means the zinc has been removed, I will need some other oil to keep my 440's flat tappet camshaft and lifters alive and well.

      I'd really like to try the Brad Penn oil, but I'm having no luck finding out who sells it here in Phoenix AZ. I guess that I will check out their web site listed above to find out.

      I just read a post on the 62-65 Mopar site that said Castrol 20W50 is now formulated with higher zinc for collector car engines.

        Chevron Delo 400 15W-40 is good oil, has plenty of ZDDP in it. The Rotella T has gone down the tubes unless you put in some additive, I use GM EOS. Those conventional oils (Castrol, Pennzoil, etc, I use no more). I'm switching everything I have over to the Brad Penn oil come spring time. It's pricy at $5 per quart, but well worth it.
