I've started trying out boosting my 16% total-oil (80:20) fuel to 20% total-oil with Lube Booster which also changes the oil blend from 80:20 to about 60:40. Apparently racing fuel uses 60:40, but I'm wondering if there's any problem with using a 60:40 blend for normal sport plane engine use.

The 46LA engine that I've been using the fuel in has been running fine, but wanted to check before I use the oil boosted fuel in my 46AX.

If it's a problem to use 60:40, I can of course do the boosting in future starting with straight synthetic fuel to achieve about 80:20 after boosting.

Thanks
