In that case you just have to find a Ford approved oil that contains lots of boron per @aw081271Perhaps, but doesn’t Ford reserve the right to 86 the warranty on engines that have run additives? I’m not looking at the owner’s manual but it seems I have read that.
Remember, they don’t have to prove it caused a problem; you have to prove it didn’t.
