Looking to see what oil everyone recommends for my 63 Valiant. She is stock, just plan to drive here to and from car shows and a bit around town. Not sure when here last oil change was, so I am planning on possibly tossing in STP. Before I go ahead and get the oil I wanted to see what recommendations are out there. |

5w-30, any brand with the API seal, synthetic if you can afford it. No additives. |

10w-30 regular (mineral) motor oil. no additives, API rated. No need to spend extra money on advertising gimmicks, or "upgrades" you don't need. |

Check out bobistheoilguy.com for recommendations. I'm a member there and it's like drinking from a fire hose sometimes, but there's a lot of good information there. My personal choice for an occasionally driven vehicle is Pennzoil yellow bottle in the viscosity Mopar intended. Oh, and avoid Fram filters. |

...if you want to head down a rabbit hole of opinions, many without basis in fact, all put forth as gospel truth. There's definitely some good information to be had on that forum, but the signal/noise ratio is awful. And a large proportion of those on the board who do have some actual knowledge to back up their assertions are either not objective (because they're Amsoil "dealers" or have some other interest in pushing expensive boutique oils) or they're into spending their time and money geeking out on arcane details and differences and specifications that will make exactly zero practical difference in how well their (or your) car runs or how long it lasts. That's fine; I'm not in a position to judge them for it—just ask me about headlamps sometime—but to listen to their advice you'd think you absolutely must spend a fortune on specialty oils or else your car is doomed (DOOOOOOOOOOMED!) to die the day after tomorrow. Horseapples! There's a bunch of half-informed noise about how modern oils are inadequate to prevent flat-tappet engines like ours from grinding themselves into heaps of slag. That's not correct, and it's just one of a long list of myths about every aspect of oil. Fact is, almost any reputable-brand oil you can buy today (excepting the cheap crap at Wal-Mart, no matter whose name is on it) is vastly better than what you could get ten years ago, let alone back when our Slant-6 cars were current items. The second and fourth posts in this thread contain good recommendations. Select your viscosity according to the condition of your engine and the conditions you drive in: if the engine's old and worn and/or you drive in very hot climates, use a somewhat heavier grade. If the engine's tight and in good shape and/or you drive in cold climates, use a lighter grade. Only use a very heavy grade (SAE 30, SAE 40, 20w50, etc) on a thoroughly whipped old pony you're trying to get the last few miles out of. Use a good-quality filter and change it every time you change the oil at a reasonable interval (3000 miles is too short; 10,000 miles is too long…make your choice within that range in accord with the type of driving you do—more highway = longer interval, more stop-and-go = shorter interval). And leave the perpetual religious quarrel over oil to those who get their jollies participating in it. |

Dan not trying to reopen this whole thing nor debate the number of angels that can dance on a sewing needles head....just one simple question... would it be advisable for my solid lifter motor to run a good synthetic like mobile 1 without the special zinc cam lubricant? (the motor is in excellent condition with about 10K miles since a full stock rebuild) I am currently using Valvoline 5-30 with some zinc additive. In all my newer stuff I use mobile one and have been extremely pleased would love to run it in my slant just unclear about the need for the cam additive thanks dean |

Stock rebuilds are fine with modern oils including synthetics and no additives are needed. I've changed most of my equipment to Mobil 1 of one variety or another. |

Yes, a reputable-brand synthetic is not only fine, but also quite a bit better than conventional oil. These days I use Pennzoil Platinum, but Mobil-1 is good, too -- there is no need to spend extra money for boutique brands you have to go out of your way (or get with a "dealer") to buy. No you-add-it additive is needed or beneficial.

One caveat to my "no additive" recommendation is if you have a motor that has sat and has sticky hydraulic lifters or partially clogged rocker arm oil passages, Marvel Mystery Oil works well to unstick and unclog things. But other than MMO (and only when necessary), no additives for me. |

Yes, in certain circumstances a thin cleanup additive such as Marvel Mystery Oil or Rislone can be put to specific use, and in cases of very severely sludged engines that will not be taken apart for a proper cleandown there's a pain-in-the-nuts procedure that can be used in fairly good safety (or you can take shortcuts and risk your engine). But additives claiming to "improve" one or more aspect(s) of an engine oil's performance should be left on the parts store shelf. |

one of the threads mentions NOT using a Fram filter on the /6. May be old discussion, but I'm new. What suggestions do you have for ones to use. Thanks |
