Vehicle: 2011 Toyota Avalon Limited Engine: 3.5L V6 Engine oil capacity: 6.5qts Oil type: Mobil 1 5w30 SM formula Oil additives: None Gas Additives: None during this run. Make up oil added: None Oil filter: Toyota TRD Oil Filter. Air filter: OEM Toyota Air Filter. I opened the box and dusted the air filter of bugs and loose dirt and plan to use it for another run. USE: highway/city @ 40/60. The car didn't get much abuse during this run and was driven "normally" by my parents. I'm all out of the old M1 SM formula and refilled the beast with a 50/50 mix of Mobil 1 0w40 and 0w20 EP. I don't plan on sampling anymore and will continue "blindly" with 10k intervals until we decide to trade the Avalon for something else. p.s. this run was 2x the mileage that Toyota recommends (which is 5k intervals).
