Synthetic VS. Regular oil reliability - Toyota Yaris Forums

severous01 · 01-01-2010, 10:52 PM

i usually add 25% to my synthetic oils...however, with the lower costs of the 5q buckets at walmart and the fact that this thing only takes like 3.5q of oil, every 2 oil changes i have an extra oil change for even cheaper.

surprisingly, my fuel economy keeps going up. now i changed my oil at the first interval. i immediately switched to syn on first change. i guess the engine wasnt broken in and it's slowly breaking in with the synthetic oils. any way, i'm happy seening as how my oil isnt even ready to be changed when i drain it. it's still a dark amber color, not anywhere near black or dark brown like i see most of the time working at a dealership.
