FWIW my comment was not intended to be applied to a fresh, healthy engine.

flat tappet cams have a 2*-3* taper on the lobe to rotate the lifter, which has a convex surface to ride the taper. worn cams lose their taper and lifters lose their convex to eventually become concave, how they manage to continue rotating in that condition is beyond me but they do for a while ...

why? IDK, lobe offset? but it isn't much

no way to tell the condition of a high mile engine that may be ready to stop rotating the lifters, also no way to positively tell whether the new slippery mixtures were the cause of the high mile flat tappet fails but some people thought it was more than a coincidence. cars died on their first synth oil change, and of course that was pre-internet so there's no digital trail. not exactly a bragging point so no oil company is going to promote the shadowy history.

no argument today's oil is pretty awesome stuff Smile

Well, I certainly learned a lot! So, modern 5W30 is okay in my Torino? I don't want to spend much money on this car. It's not worth it, and I don't drive it too much.

I agree that spending a lot on this engine wouldn't be the best move. There is no advantage to running a 5W30 in your situation.  The 5W30's only advantage over a 10W30 is that it flows better in cold temperatures.  You don't have that issue in Florida.  Further, in general a 5W30 will shear (thin out) much faster than a 10W30.  This is more of a concern with old carbureted engines that generally have its oils diluted with gasoline.

I think your best choice would be to use a 10W30 oil with lots of ZDDP (Zinc and Phosphorus additives, which are needed for flat tappets) .  Personally, I'd run Shell Rotella T4 10W30.  It's cheap, will offer lots of protection to your flat tappet cam, and can help clean up your engine a bit with a short oil change interval.  The HDEO (Heavy-Duty Engine Oils - diesel oil) are very robust and work well with old engines.  Another brand of 10W30 HDEO would work fine too.

 
Modern conventional oils are made for modern cars with catalytic converters and that don't have flat tappet cams, so they are not ideal for older V8's IMO.  You can use it but there are better choices.
 
If you are unsure or unwilling to run a HDEO, then at the very least run a high mileage oil.  Quaker State Defy has a healthy does of ZDDP.  It also has some additives to help with seal conditioning.

Well, I ask because I choose to have a shop change my oil (because it ends up being cheaper), and I think they use 5W30. I can ask if they have 10W30 for the same price. For me, it's about cost. I don't plan on keeping this car much longer, but I do want to take care of it.

Yes, if that's the case, then ask for 10W30, I am sure they have it.  See if they have a high mileage oil option but it might cost you a couple of extra dollars.
 
Why not change it yourself though and buy the oil you want?  It would save you money and you could do another video.  These cars are SUPER easy to change the oil on.  We can help you out on doing the job if you need help.

I didn't know you guys actually watched my videos! Haha. I do it simply for cost. I get a discount at my local shop, so for $23, I'm out the door. I can do it, well... Never tried in my Torino, but for me, it's just more effective to have someone else do it. High dollar work, like mechanical work, I'll usually try myself if it's in my comfort range.

I definitely appreciate the offer for help. This forum has been one of the friendliest I've been on.
