AMITHUX

first of all thank you for your really satisfy and clear answer. i have another issue with some parts that i wanted to order from Amazon because the prices in israel is higher than usa even with shipping. the seller say that he dont know to say if the parts like oil filter ,atf filter ,air filter ,fuel filter are matches to my ej16 engine and to my 4eat trans because this kind of subaru does not sell in america . i hope someone knowing better to say in this forum if the parts are matches or not. Thanks.

Hello to everyone. I am talking about Impreza 2004 1600 (EJ16) Auto . the vehicle is in a very good shape with 98.000 Kilometers. i wanted to change my oil viscosity from 10W-40 to 5W-40 100% Synthetic in my next maintenance. in first thought in the maintenance book write that only turbo engine refill 5W-40 and in mine is 10w-40 "Semi-Synthetic" oil. in second thought i know that the 100% synthetic oil is better almost for all engines and the previous owners filled a 5w-40 oil in the past too. i am confused and its important for me to hear what you guys have to say about it.
