i drive my IS300 hard all the time and it has 56k on it. im just switching into mobil 1. how long does it last till the next change. sorry to bother most of you guys. by the way is the toyota oil filter better than after market?
synthetic should last longer than non-synthetic ones, tho i still recommend changing it between every 3000~5000mi.
use lexus V8 filter(part #90915-20004), it has greater capacity than the original one. just make sure you put enough oil, as the V8 filter holds more oil. the Mobile1 filter is exactly the same thing as the denso made (jdm)toyota one, so i wouldnt waste my money on it.
