Advanced Durability 10W40

Recommended blend: none

SLR-3 Scoring ---

N/A: did not complete

This oil destroyed the testing machine in less than 20 minutes. It could not handle for 20 minutes the same exact testing that every other oil has been subjected to for 120+ minutes. The wear and heat generated caused horrible scarring and even started to overheat and melt the cylinder. Do NOT use this oil in any engine!

Quaker State Advanced Durability 40x

Listed as 40x but used digital zoom on the camera to focus on the scarring. Actual zoom level was closer to 80x.

Ultimate Durability 5W30

Recommended blend: M17

SLR-3 Scoring ---

N/A: 63.69
M7: 69.84
M17: 86.76

This oil had average component wear, but higher than average temperatures and required power resulting in a lower base score. Previous SQUID INK blends had relatively minor impact on performance in comparison to other base oils, so a new formula was developed specifically for QSUD -- M17. With M17 the performance was improved a fair amount.
