Liqui Moly of Redline 75W90

[Thugzy]

After shopping around I can get Liqui Moly or Redline 75W90 at the same prices as M1, PP and Castrol

Out of the two which is better for my Crosstrek, Q50 and F150? All require GL5 and all have open diffs (no LSDs)

Redline has Friction Modifiers

Liqui Moly no Friction Modifiers

Thanks!

Based on experience, I would still rather use Mobil 1 75W-90.

Does your F-150 specify 75W-140 in the rear axle, or has this recently changed?

Redline GL5.

Looks like it changed 2015+ ..... both my trucks specify 80W90 in the front and 75W90 in the rear

Redline lubes are by far one of the very best. many manufacturers have been downgrading to thinner lubes as per big-brother aka government recommendations!

For the same price, I'd probably choose the Red Line. I'd also toss availability in there as a concern, too.
