    Yes you just want to use some cheap dino oil, only used for the break in period.

    Yeah that would be fine. I just bought 5 quart jugs of 5w30 for under $10 each to flush out my engine, I have 4 quarts of Redline 5w30 waiting to go in after.

    Re: rebuilding engine

    how long do you usally spend breaking in a motor with an audi?

    With the rotaries it was oil change at 500, then 1500 then 4000 for the 'break in' stepping up your max rpms 100 every 1000 rpms'.

    Re: rebuilding engine

    Just drive it like a normal everyday car with a lot of engine braking. 500 is fine. You just really need to seat the rings. Make sure the oil you are using is detergent free.

    Engine braking for the bearings. I would wait to atleast 500 miles to change the oil for the first time and before going full boost/throttle. Then, just switch to synthetic at 1000 miles.

    Re: rebuilding engine

    is engine braking bad because I think I do it a lot. should I just put it in neutral and coast while applying brakes or is it okay?

    engine braking is good. When you are coasting in gear you are also saving gas.

    Re: rebuilding engine

    If your car is new and factory-filled with synthetics, DRAIN IT and put in your plain ol' Castrol GTX 5w30 "dino" oil
    FUCKK! I just wasted like $30 bucks...fuck my life...

    Re: rebuilding engine

    read that link Dougy posted above , it's good shit. The first 20 miles is where 80% of piston ring seal take place, so you do want to get on it and do engine braking right out of the box.

    I did my oil and oil filter changes at: 30 miles, 100 miles, 250 miles, 500 miles, 1000 miles. I used castrol gtx 5w30 that come in the large 5qt jugs. germanfilters.com has 10 packs that get you down to ~$5 each. The first oil change between 20-50 miles is the most important. Do not use sythetic for break-in. It's too slippery and can cause improper piston ring seal...which = blow-by, which = less power. Keep the synthetic around for after break-in. I'm switching back to syn mobile 1 0w40 at ~1500-2000 miles.

    Re: rebuilding engine

    on second thought, I might not go with mobil 1 0w40 after all. Do some searching on oil lab analysis on it and you'll understand. The flash point kind of sucks for this "high quality" sythetic oil... Redline or Motul might be my choice now, just harder to get. Motul 0W40 looks promising.

    bobistheoilguy.com has some good discussions about oil.

    Most high end V8 shops usually sell Redline, I order my Redline from Summit.

    i've used this method for a while. i only do oil changes @ 50,300,700,1100. the first 50 mile oil change is super crucial. the oil has so much mini metal shavings, it looks like glitter sand suspended in the oil. this method works great.

    Re: rebuilding engine

    Mike, would you say that the extra costs to get the Motul 300V is not worth it over the Redline?

    I think I'm going with 5W30 instead of 5W40. Both of these 5W30's are such high grade oils that I do not see a problem at speeds above 100mph. I would rather have the lighter weight of oil for ease of turning over the crank. That should also help the turbo spool faster...

    i'm broke too, i'd probably use it for 50 miles to wash out assembly lube and shavings then drain it then go convo oil. at least you used it!

    I don't think its worth it. Do you really think you'll notice the differences between a 30 and 40 weight oil when the oil behaves in that end of the viscosity band?

    I am going to switch over to Motul Specific 505.01 502.00 505.00 5W-40 when my new motor is ready for synthetic. No more Mobil1 for me.

    The cost of motul was just too much for me. The spooling part is one of the reasons I am going with 5w30 Redline, plus my oil temps never get above 175 during my runs at the drags. Just make sure that you dont go to thin for the oil temps you see, redline suggests running 30 in any car that runs below 225 deg oil temps for a long period of time.

    You could do that, just make sure to use plenty of painter filters when you filter the oil before putting it back in later. No use on wasting good synthetic oil if it is brand new.
