I have Toyota Sienna 2007 LE and have change the engine oil 1 week ago and now I need to use Sea Foam Spray for throttle body cleaning. Do I need to change the engine oil after using Sea Foam Spray?
2. What amount of Sea Foam Motor Treatment is good to put in engine oil for Toyota Sienna V6?
3. I need to use Sea Foam Trans Tune for flushing the transmission fluid. When I add the Trans Tune in transmission fluid and drive it for about 30 miles and is it enough to drain the transmission fluid form the pan only or I need to take it to a shop to drain the whole transmission fluid by machine?
Thank you so much!
