After some opinions on what oil I should use to run in my TT. Has had a full rebuild with forged internals. Also some advice on first start up would be good, ie do I let it idle (or set rpm) for while (for how long) before driving etc. Cheers guys, not far away now. And yes I did search and no I didn't find what I was looking for.
That's a good article mtenori, thanks. So basically let it warm up completely than go hard, but sensibly and methodically. Still no wiser on which oil to use though.
Hey mate Best to use a mineral oil rather than synthetic. This is due to the piston rings and other components needed to "bed in" and synthetic is usually too "slippery" and doesnt allow this to happen. Run the engine in for 1000kms and no more than 1500kms, at which time you should change the oil filter and also switch the oil to a suitable synthetic type. Also at this change drop the water out of your coolant system, and fill it up with coolant.
i always use running in oil on n/a engines that have been rebuilt because it has no friction modifiers and no anti wear properties which reall help the rings cut in. I dont know about a turbo'd car though becuase it might wear out the turbo bearings, it is someting i am thinking about for my turbo'd engine rebuilds too. At this stage i would say run it, but only for 400 to 500kms
I can't remember who but a few companies make oil specially for engine break ins. Might have been motul/redline/one of those brand names.
I used a "running-in " oil for 1k, a multi-grade mineral for 5k, now Mobil 1 5-50. drove it "normally" until the first oil change ( without really pushing it), then just gave it more work, a lot to do with that was being a bit tentative(as you are after spending that sort of money and time), now 11k, including a 2.5k weekend down to W'gong, and all looks well
Thanks guys, I was planning on using a special run in oil, but like rollin wasn't too sure how this would effect the turbos. I think I'll go with that though if others have used it successfully. Any opinions on brands?
Have often heard people talk about running it in how you would normally drive it. That article sure does make a lot of sense and admit I will probably follow it to the letter.
everybody u meet has a different method of running in, IMO just stick to what you know. personally for the first 500 kms i use running in oil, dont take the car over about 75% of maximum rpms; do a few pulls up to high rpm and then close the throttle and let it decelrate heavily to create a real strobg vacum in the cylinders. On big boost F/I motors i wouldnt be hitting any big boost till well after 500kms
For brand i recommend Penrite running in oil, retail is around 10 bucks a litre i think. Ill give the penrite rep a call at work tomoro and ask him about running in oil on a turbo'd engine
hahah, just read the article now, some of it is good but some is just a crock of b.S, this picture for example is just laughable the one on the right is apparantly after a full race season! there is obviously alot of other factors in play here. That aside, the other thing that TT owners should be aware of is the heavily rich mixture that might accompany these full load pulls. that amount of fuel really washes out the bores and is not good during the early stages
I asked this question yesterday, and was told Castrol Magnatec would be used for the run in of my engine, dumped after 1000k, and refilled with the same, that?s what the builder recommended. I asked if using a different brand oil like amsole would be ok, he said yes that?s ok, as long as I used it at every change. He said nothing about using a mineral based oil, or a running in type oil. I assume he knows what he is talking about, having rebuilt many Z engines over the past 15 years or so.
Hmm, I've read alot about using oils that aren't synthetic because you don't want friction modifiers...
Went in to my machine shop today and bought some Penrite running-in oil. Says it's suitable for turbo applications on the label. Cost $19 for 5 litres.
yeah i spoke to the rep today too, he also said it is suitable for turbo'd cars BTW you got a really good price on that oil.
yeah kinda, IMO do some high rpm runs but with a small throttle opening just so u dont get those heavily rich mixtures when its hard on boost
Bringing up my old thread cause there's no point starting a new one. The run-in oil I'm using says on the bottle to change at 500km's, which is what I plan to do. This seems to me a little too early to be switching to full syn. So I'm thinking just go a standard multi-grade for the next 1000km, before switching to full syn. Does this sound right? Any other opinions?
