Question:
Has Mobil 1 Synthetic Gear Lube LS 75W-90 Changed?
Has Mobil 1 Synthetic Gear Lube LS 75W-90 changed? I've used Mobil 1 Synthetic Gear Lube in my Formula Continental Hewland LD200 racing transaxle for years. Whenever we need to change gears, the old lube would look almost as good as new. However, since this season started, the lube is black in color after a race weekend. I am not the only user who has reported this. Can you explain why this happens now and not in the past (as recently as last year)?

Answer:
We have not made any changes to the formulation. If you have an oil sample from your next drain we may be able to analyze it and find out what you are seeing. It could be due to a change in a new gear wear treatment or anti-rust coating.
