    Default Pennzoil racing oil for cam break in?

    Pennzoil GT Performance Racing 25W50 - Cs 12/1 qt

    Is this stuff suitable to break in a new engine with a flat tappet cam? The zinc levels are supposed to be very high. TIA.

    Do your'e self a favor and ask the grinder for a recommended break-in procedure. Or if you bought a pre-built deal then ask them if it was ran on a run-in stand? It really matters on what the builder did prior to your'e purchase and where to go from there! Regardless, for the first ? hours I would run a LUCAS break-in oil or atleast the additive. But again ask the builder!!!! They wont but should stand behind the product. O.G.

    YES!!!!!

    Its every bit as good as Brad Penn, Amalie Pro, and the old Kendall. Its as good as a conventional oil gets. great oil, just hard to find.

    Also be very careful on what you read! the person that built the engine should be the one to recommend how to break it in. If you have issues later he may or may not help you out! Any performance application carries an out the door warranty--- Out the door out of warranty! The closer you fallow their recommendations the better chances you have of a little help if or when stuff goes south! Good luck!!!! O.G.

    I was given an article that stated all oils have reduced zinc, even racing and synthetic oils. It says you are on false security if you think racing or synthetic oils are unchanged. they recommend half a bottle of break in oil per oil change for protection. Is this Bullshit ? I can post the article.

    I would STILL break-in a flat tappet cam with the inner valve springs removed...just give it every chance you can.

    yeah the inner springs are out and it will be run in on a test stand. I guess a bottle of the break in additive can't hurt.

    Please do not add the article! Anybody that has a clue already knows what is going on with additives and how much the good stuff is gone! It really takes a good 20 Plus hours to really break in an engine with current oils and EVERY additive you can toss in!!! I personally build an engine with a ton of moly and every bit of additive on run in. Things seem to stay together so until otherwise, I will keep doing it that way!. My lame ass opinion but I treat it like a sore dick and don't fu$k with it!!!O.G.

    Amzoil makes a special break in oil ( thats what we use ) but that oil should do just fine.

    How did we break in cams in the 60's. Anybody remember buying some bullshit break additive crap or some special break in oil? There is absolutely NOHING different about Pennzoil GT Racing than it was in 1965. If anything, its slightly better. It is one of 3 oil that are 100% penn crude oil. Brad Penn being one of the others. I would run Pennzoil GT Racing IN ANYTHING as much as any conventional oil that has ever been sold[/B].

    If I had the stuff, I doubt I would waste it on break in unless I had a good steady access to more.
    I have no trouble breaking in a cam with almost any straight weight oil. Valvoline VR1 30, 40 or 50 WT depending on what the motor wants is fine right from the bottle.

    Yes, its that good!

    Yes as a matter of fact I do! Most cam Manufactures back in the day recommended a non-detergent straight weight and added a 1 oz tub of break-in lube(to be used generously on the lifter,bores,push-rods rockers,and any related parts, and cam) and they (Crane, isky and others) Had recommended a high rpm break-in for around 20 minutes then change the oil and go! Those days are gone as is the oil we used back in the 60,s and 70.s. Here is the big surprise!!!! The additive they added to the cam and lifter kits were nothing more than a moly lube. But back then we never had a cam failure either!!!!!!O.G.

    On the flat tappets, here back in the 60's and 70's it was straight weight and a can of GM EOS. Now I seem to use a break in oil or a straight 40 and a bottle of ZDDP.... and less the inner springs for break-in.... but don't use too many flat tappets anymore

    I agree with the straight weight, and said as much in my last post. Personally I would not waste the Pennzoil GT for break in. Any straight weight Valvoline VR1 is fine.
    Of course the break lube that came with the cam, DUH!
    Your right Gearhead, EOS was common place back then and completely slipped my mind. Thanks for the reminder. Today, GM calls the stuff "assembly lube" because they can't legal call it a oil suppliment any more. It infers for normal use and it will void a new car warranty. So now its designated as an assemblt lube. Still GOOD stuff.
