The chap that serviced my Volvo V70 would use Forte engine flush before every oil change --why i dont know. We think our engines are clean because they get serviced on a regular basis .But if you have never used this flushing oil ,, then you will never know just what comes out of your engine on an oil change. You would hava a shock . Now, me , i do an oil change every 6 months . I have a bottle of Forte engine flush now for 12 months , but i wont use it for my own reason. Well i know my oil is clean . By just checking it on the stick i can see right through the oil on the dip stick and it looks clean to me just as if it was changed yesterday But i drove the car and gave it a good run before i changed the engine oil . It was then that i had a wide awakening, because the oil that came out of the engine ,,came out black .. So may be an oil additive would clean out the engine after every oil change . And some engines will need an additive in the oil before its changed .Lets face it some owners never do an oil change from the day they buy the car .
