The best oil supplement I have ever used is called Motorsilk, its the only one that actually changed how my engine ran, it revved quicker, it started quicker in sub zero temps and when the next oil change came around there was less carbon in the oil.
I religously change my oil every 1500 miles in winter (I am in Alaska) with Mobil 1 and in the summer I usually let it go to 2,000 miles.
I would NEVER let the oil stay in over 2,000 miles.
Conventional oils work well with lower-revving engines but synthetics work better with today’s smaller, higher-revving engines, which tends to break down oil faster. That’s why I use Mobil 1 for my 1998 Honda Civic HX CVT coupe, especially since the engine runs a lot at 3,000 to 3,500 RPM all day.
