false
This benefit helps with
Engine seals that have become brittle and shrink causing leaks.
Extra anti-wear additives to reduce friction
Contain special seal conditioners to help leaks
Extra detergents to reduce deposits
This benefit helps with....increased blow-by gases and deposit formation on the pistons and other mechanical parts.
Extra anti-wear additives to reduce friction
Contain special seal conditioners to help leaks
Extra detergents to reduce deposits
This benefit helps with....decreasing a more rapid rate of engine wear.
Extra anti-wear additives to reduce friction
