Incredible base oil performance. Performed better than expensive "performance" oils such as Royal Purple or Mobil-1. Low power usage, very low operating temperatures, and excellent wear profiles. All-around great results.

M1 provided great results while reducing the operating temperature of the oil. This would work well for street vehicles without external oil cooling.

M10 and M12 both provided outstanding results but with generally increased temperatures. In either case, even the highest temperature recorded was lower than that of many other base oils. If your main goal is lowering oil temperature, M1 is recommended. Otherwise M10 and M12 are well within normal testing temperature ranges (280-300' F) and provided outstanding wear protection.

Long Lasting 5W30

Recommended blend: M12

SLR Scoring ---

N/A: 66.84
M12: 87.58

Lucas Pure Synthetic "Long Lasting" produced very little and fine scarring, but at the cost of extreme heats. This is especially evident at the base oil's 120 minute reading. The primary goal of additives with this oil were to reduce temperatures, as the scarring was already minimal.

M12 reduced peak temperatures by 40.8' F and required power by 10.85%, while also reducing peak scar size by 13.68%. The relatively low scoring of Lucas Long Lasting (N/A scored 74.46 out of a possible 100) is due to the high heat and high required power observed.

One unusual result is that this particular oil leaves a brown residue in some areas. This was the case for the base oil as well as with all SQUID INK blends. One of the ingredients in the base oil leaves this residue. How it affects long term engine operation is unknown, but it likely has no negative effect.
