Aoa,
I would like to share my experience with PW's about "Leppon" oil filter.
Last week I took my Vitz 2003 for oil change, when the oil was drained I noticed it to be pretty dirty.
So I decided to give engine a quick flush; change after 1000kms.
I purchased oil and asked the shopkeeper to suggest good oil filter. He showed me Leppon which was true copy of Toyota OEM filter 90915-10003.
The next evening my servant told me that Vitz was dropping oil, I thought he was mistaken and was referring to AC condensate.
The next morning as I was to leave for office I noticed the servants cleaning the drive which was covered with fresh oil. I was told it was from Vitz. As the car is driven by my son I called him and told him to take the car to 3S.
Imagine; the filter was fully tight but it leaked oil as soon as you rev the engine.
Luckily, the car has lost just 1 ltr..................
My 1st and last experience with non OEM filter.
PLS stay away from these filters...... I was very lucky.
