Ben2k9 Posted August 16, 2018 Report Share Posted August 16, 2018 It says oxygen sensor should be cleaned every 20 hours when running this. I wonder if 25 would suffice to coincide with oil change interval of running 100ll? Link to comment Share on other sites More sharing options...

iaw4 Posted November 12, 2018 Report Share Posted November 12, 2018 I do have an oxygen sensor in my brain, but presumably it won't need cleaning every 20 hours. when should one use decalin? always? just with 100LL? just with the new 100VLL? just with Mogas?

andyb Posted November 13, 2018 Report Share Posted November 13, 2018 If, for example, the tanks have 10 gallons of mogas, and I add 5 gallons of 100LL avgas, would I still be able to add Decalin to mitigate the impact of the 5 gallons of 100LL in the mix? How much Decalin would I put in? Thanks, Andy Link to comment Share on other sites More sharing options...
Roger Lee Posted November 13, 2018 Author Report Share Posted November 13, 2018 It may help, but I truly don't know if the 91 oct. would mitigate the 100LL lead and at what concentrations it would take. Bottom line it wouldn't hurt. Link to comment Share on other sites More sharing options...
