I personally, Use 5w30 oil for this type of car but for the last service I used 0w/40 because the car parts store put the Reg No in and it came up as 0w/40 oil grade for this car lol so no question asked. But well done for pointing that out. Cheers buddy. 😉👍
Yes all the Toyotas have fuel filters however, Most of the newer Toyotas models don't need to changed them because they are lifetime. But if you want to change it you can. The fuel filter is located underneath the car almost near the rear door where your fuel tank is.
The warranty usually covers your vehicle only if you service your car in a garages which are recommended by the main dealers or seller and service your car on a regular basis with a service stamps on your service book. If you miss a service which has already been passed the due date that will automatically nullify your warranty. However, The warranty on cars are all varies such as, Aftermarket warranties etc. If you do not care about that then DIY service 👍😊 thanks
