Hello again!
Are there any members here with 460ci Ford experience? The search engine makes me add another word to "460" in order to bring up any results so I tried numerous combinations, truck, ford, etc, with zero luck obtaining anything relevant.
This car is from 1976, and very heavy. The owner's manual is calling for 20W-40 and 20W-50 for temps above 10*F. I checked the Ford parts website for revisions or updated recommendations but there isn't oil or fluids listed for my year range. I know the 460 spanned more than 3 decades, so I'm assuming tolerances, clearances, valley hole locations, oiling systems, etc, are different depending on year, so I'm reluctant to look up the specs for a 1996 460 motor and just go with what it calls for either.
The car it's in will be driven casually, rarely, and the most revs it will see would be spirited highway on-ramp acceleration followed by a gentle drive at 75-80mph down a quiet rural 4-lane highway to a town an hour or so away. More wear will probably occur at slow speed short events like parades and car shows. I'm going to modernize the engine a little this winter to get rid of the 70's era concepts of efficiency and smog reduction. Altering the rear gears from 2.75 to 3.55 will raise the revs some but this engine will still be far from abused.
My question is mainly viscosity weights. 20W-50 or even the lighter spec 20W-40 seems wildly antiquated. The manual does spec of a 10W-30 in temps under 10*F, but there is an asterisk that says if towing or driving for long periods is going to take place then to not use it.
Does this motor really need something that thick? I'm a fanatic about clean oil, this will probably be changed twice just in the summer. There will be no winter or cold weather driving. I do have some Porsche spec 0W-40 laying around, I think it's Castrol brand and can get more.. but was wondering if a fully syn 5W-30 or even a 5 or 0 W-20 would work. What's been your experience? What do you run in your 460? I see a lot of people running thicker stuff in these motors but they're all modified and used for racing, marine use, or mud truck racing. Suggestions of old large engine oils will be highly appreciated. I look forward to reading everyone's input.
Thank you!
