|
High Mileage oils are formulated for older engines with over 75,000 miles on them. And High Mileage oils include “Seal Swell” chemicals to help reduce oil leakage in those older engines.
Below is how 5 different High Mileage oils ranked just among themselves, regarding wear protection capability, after they were tested.
Below is how 5 different High Mileage oils ranked just among themselves, regarding wear protection capability, after they were tested.
The Wear protection reference categories are:
.
• Over 105,000 psi = INCREDIBLE wear protection
.
• 90,000 to 105,000 psi = OUTSTANDING wear protection
.
• 75,000 to 90,000 psi = GOOD wear protection
.
• 60,000 to 75,000 psi = MODEST wear protection
.
• Below 60,000 psi = UNDESIRABLE wear protection
.
• Over 105,000 psi = INCREDIBLE wear protection
.
• 90,000 to 105,000 psi = OUTSTANDING wear protection
.
• 75,000 to 90,000 psi = GOOD wear protection
.
• 60,000 to 75,000 psi = MODEST wear protection
.
• Below 60,000 psi = UNDESIRABLE wear protection

As you can see, these oils all performed very well, even though the top 3 are modern low zinc API SN oils. And that is even more proof that oils DO NOT need high zinc levels to provide excellent wear protection.
