    hi guys,after a long time I'm almost ready to start my engine, it has been resting in my bedroom for far too long, I would like to have a comparison, with someone who has had the opportunity to try different engine oils, different grades,the tolerances that were found during the reconstruction were from 7 to 7.5 cents (central bearing with shoulders) for the crankshaft, and 6.5 cents for the connecting rods,on based on, what do you think would be the ideal oil to use so that the pressure and the passage in the ducts is optimal, fast, and reliable? running-in included

    10w 50
    10w 60
    15w 50
    20w 50

    the car after will be used for the city and to do Drift

    It would also be nice to know your bearing tolerance, and your oil

    below I leave you a photo of the engine and its specifications, (yes I know, the pulley of the water pump is mounted upside down, lol,but the picture was too good for me :D)
