My 2014 Toyota Venza AWD V6 needs LS gear oil in the transfer and diff. Previously, I have been using Mobil 1 LS gear oil with no problems.
Now I want to switch to Mobil Delvac™ Synthetic Gear 75W90 + Red Line friction modifier. Red Line suggest a 4% ratio.
What does the forum recommend for the mix ratio?
