Triumph TR6 - break in oil
|I know that I must have this info somewhere, but I also know that one of you has it deeply embedded in memory from recent experience. What grade/type/viscosity/etc. oil should I use to break in a newly overhauled engine? How long do I run it before changing the oil and filter and how do I run it, that is vary the rpm, not letting it run at any one speed for very long or what? Thanks all. Also, I guess it's a given that I should add ZDDP to each oil change including the first one.|
|Your ready to start that beast finally.|
Instructions that came with my new cam didn't specify grade, so I just used the standard issue Castrol GTX 20W50, with a bottle of ZDDP added. The instructions were intial start-up should go straight to 2000rpm for 20 minutes (my neighbours loved that part!), then change the oil and filter. It said it was okay to stop and re-start the engine if necessary, which was good, as I had a problem with the bottom radiator hose, which popped off the new stainless steel pipe - I was sitting in the driver's seat congratulating myself for getting the engine rebuilt and running, when I saw a pool of coolant under the car (at first I thought it was oil in the limited light under the car which had me really worried!) - good thing I hadn't fitted the gearbox tunnel at that point... Fortunately the temp gauge hadn't even reached 1/4 by that point, so I think I got away with it.
After that initial oil change, there seem to be two schools of thought on breaking in. The old-fashioned carefully varied engine speeds and build the rev-limit over hundreds of miles (which I fully intended to use...) and the drive-it-like-you-stole-it approach, which several people on the internet (so you know it's true!) say is the best way to bed in rings etc. to ensure maximum performance from the engine.
|30 weight. Nothin fancy and pour some stuff in. It's only gonna be in for 20 minutes then throw in good stuff. Check to see if you can get Penn Grade#1 Racing oil.|
It's got all the good stuff.
Now don't get Rick started.
Let's start a pool! Does Doug Baker's car drive before Don Kelly's????
Who's in on this??? I'm takin' Doug.....
Just answer the hard top question.
I already emailed him with the links.....
|Is that all really "break in"? I thought it was 500 miles with a conventional oil, going up & down with speed, then a change out. After that it was additives, syn, ect.|
|I'm no engine builder Doug but I will tell you what was done with mine after a rebuild with positive results.|
20 minutes at 2000 rpm with Castrol 20/50 then oil was dumped.
Fresh refill of same followed by a drive at varying speeds across Canada from BC to Ontario. I think we drove 4600 kms whatever that is in miles... multiply by .62.
Ever since, my annual Castrol 20/50 oil changes include a quart of Lucas Oil Additive plus 4 oz. of GM's EOS per Rick C's advice. I also add lead to my fuel.
No problems touch wood!
|Why put expensive oil in for 20 minutes. The main thing that it has all the proper certification and add ZDDP to it.|
|Don, Thanks. YO may be H, but it's tried and true.|
Rod, perhaps the pool should be if we either will get this done in this lifetime or have to bequeath an incomplete restoration to grandkids!!
|Glad to see I got one guy on this site trained.|
My vote is for Doug. I think Don is packing his up and goin south.
