Which Red Line oil do you use? The SAE20 is the closest to 5W20, is this optimal? Do you leave it in for 10K-18K miles? What about tranny oils?

 

for me, oil every 3000 - 3500. i change the 'mtl' every 15,000 or so.

why do you use redline? honda supplied oil works good enough...

i replace mtf 20k miles for the first 50k miles, and then switch 10k miles after i pass 50.

 

What are the benefits from using a slightly heavier mtl in the tranny? I have just purchased MT-90 (70W-90) by Red Line. It is slightly thicker than the OEM or OEM replacement fluid(70W-80). Is this better? Worse? I have been led to believe that the MT-90 is slightly better than the regular MTL? Your thoughts?

Also, why are you guys replacing your MTL at 15K intervals? Honda recommends every 6yrs/120K. You are no where close to that. Every mechanic/performance shop says that if you change that often, you are wasting money with NO benefit.
