I found some Lucas 20w50 motorcycle oil on a killer closeout at Schucks so I bought several changes worth. My FJR calls for 20w40 oil, so I bought some Lucas 5w20 oil to mix in and thin it down some. I used 3 qts of 20w50 with 1 qt 20w40. I changed the oil a bit early since I wasn't exactly sure what the mix would do and I had heard some mixed opinions on Lucas

Nice improvement in wear and fuel dilution. None of the wear metals were really out of line last sample, but we always like to see lower wear. The shorter oil run helped in bringing wear down, though if you wanted to go longer on the next sample, we think you easily could. Fuel was still present, though 0.8% is easier to take than 1.5%. With any luck it may just disappear completely next time. The viscosity was low for a 20W/50 and this is partly due to the fuel and partly due to the 5W/20 you added so it's not a major concern either. All in all, a good report.
Overall, I agree with Blackstone the report looks pretty good, even accounting for the short miles I ran this oil. Based on this, I'll certainly leave the next change in longer and maybe not mix so much of the 5w20 in. This is the second analysis I've done on this bike and the sure seems to come out thin after very few miles.
The add pack looks a little weak and uses a lot of Boron... What's that for?
