FAQs

Can I use this in older F150/F200? Yes, but not required—10W-30 4M is fine. 5W-30 shines in cold water or if you want max efficiency.

Mixing with 10W-30 4M? Yes – fully compatible, but top off with 5W-30 for best results.

Better than Sierra or Quicksilver synthetic? For Yamahas? Absolutely—Yamalube 4M is the benchmark every aftermarket tries (and fails) to match.
