Yeah,

I used to "truck" too! Same with gasolines.......for all those people who "Only use Chevron because it's better than Arco" ........I used to watch the gas trucks load up in a Bakersfield (Mohawk then Getty Refinery, then Texaco, then Chevron Texaco, Now Shell...... or who knows?) and you couldn't count the trucks loading up in the morning............every name....... plus "no-names".........

Up here in the NW.....Chevron gets their gasoline from the former Texaco, Arco now BP Refinery....I donno who they are this week!!!!

Oil is traded around like all other commodities. The additives are made by a handful of companies like Lubrizol, Shell Chemical, Castrol and a few others.

When you buy oil, there's really no way to know who actually made it because that can change frequently. It might have been Conoco Phillips this month but could be Chevron next month.

So buy whatever makes you feel good. If you really want to know what's in it.....instead of believing what people on the internet tell you....send a sample to a reputable lab and get it tested. But buy a lot.....because if you test it months later, it may not be exactly the same.

Bottom line? Buy a name brand oil. Change it 5000 miles or once a year. You'll never go wrong. Old engines became "sludgy" in the old days because people used non-detergent oils and didn't change it frequently (or in some cases AT ALL!!!)

These oil threads go on and on.....on all the automotive, marine, motorcycle, lawnmower etc sites because oil is an emotional thing!

Cheers,

Rick

As reported in fordtrucks.com Motorcraft oils have always been produced by Conoco/Phillips and have a standing contract with them,the "new" Rotella has almost 200ppm less ZDDP than Motorcraft 15W40.

When I was still trucking I used to haul oil from a Sun Oil refinery in Tulsa.I watched them make almost any brand of oil you can name,including many of the other oil company brands.Amoco,Phillips 66,Conoco,Texaco to name a few.I saw brands ranging from John Deere to Harley-Davidson to Volkswagen being made there.Also Motorcraft,Mopar and GM oils.Many others!All made from the same oil,but I presume with different additives in some of the brands.

For what it's worth I believe Motorcraft oils are manufactured by Shell.

Recently ran in to some oil facts,Motorcraft 15W40 Diesel oil was 1380ppm ZDDP also available at Wally World around $15 for a 5 quart jug,Motorcraft filters are there too.If you do some Google research on ACCEL you will find it is what it is,CHEAP! Motorcraft and Ford Good Idea!

Yes there is.....but I cannot say if you'll add too much.

There's a LOT of opinion on how much is too much or enough........There's also a lot of info out there on whether 10W-40 (non-syn) oils have too much vi improver too. Some manufacturers recommend against using 10W-40 oils and some threaten to void warranties if it's used..... (my 86 Ford 6.9L Diesel Owners Manual specifically warned not to use 10w40) http://micapeak.com/info/oiled.html



More info http://www.ttalk.info/Zddp.htm





Considering how few miles I am going to put on my 292 in a year, I'll probably use Mobil 1 0W-40t since Mobil indicates that it does have adequate amounts of zddp for flat-tappet engines





You gotta love these oil threads! There's as many opinions out there as there are people!!

Is there such a thing as to "much" ZDDP? I'm running 10w40 and I was going to add a bottle with it.

My owners manual for my DOHC 4.6 recommends 5W-20 oil for this exact reason.  It doesn't need any thicker viscosity or ZDDP.

Big Lots also carries Accel oil.  $2.00 per qt., but I havent used it.

The generalized answer to your question is Yes.  Any SFI rated oil with over 30 in its viscosity classification will have the necessary zinc/phosporus (ZDDP) for the flat tappet engines.  Straight weight SFI classified oils in any weight will also have the necessary amounts of zddp as well as any oil that says Racing or High Mileage on the labels.

Here are some past threads discussing oils.  Doing a search for 'ZDDP' or zinc will also net some more.
