Kindly advise. I was using 5w30 total in civic 2004 exi prosmatec. It had engine and transmission leakage. I had the seals replaced, and now Alhamdulilah the leakage is gone for good. I have a very strong sense that my meter had been tampered before buying (meter shows 107K kms atm).
Problem is, i dont know if my engine was consuming oil, or the oil was reducing due to the leakage, around 3-4 seals were replaced and tranny was dismounted from it's place to install new seals. Ab I'm using 20W50 (API SF). Will it be wise to find the same viscosity oil 20W50 but in a better grade? Like API SN? Another reason for me to use 20W50 is that it'll make up for the excessive wear and tear for the engine, again, since the previous owner treated this car like nothing.
