motor oil
i used 5w30 since new, when i finally hit 100,000 miles i went to valvoline max life high mileage 10w30....... but because of the exchange rate down here, all imported motor oils are not being ordered.
so i flushed my engine oil (5 minutes) with a mexico nissan engine cleaner and added mobil 1 synthetic 5w30 ... i have 8 fram oil filters left wich i was not to happy with the synthetic oil flowing through it.... so i ran truck for 130 miles with fram and replaced with bosch and topped off.
i change my oil every 3 to 4k and was surpriced at the oil/dirt color that came out from the engine flush.
3 weeks ago went out of town and got 20.+ mpg highway and after the mobil synthetic i got 24.+ on same trip.
