I am a long-time Rislone user...never had to use it to "fix" anything but I used about once a year in place of a QT of oil at the time of an oil change as a preventative maintenance thing to keep my engine clean...the only motor I ever had to open up was 150k and looked spotless but it had GTX every 3k also
Anwyway, I have always been intrigued by MMO and figured it much safer to use in the crank case than SeaFoam or B12 but versus Rislone, I still feel safer that Rislone might be the best choice for "gentle" cleaning of a motor verses MMO?
I know many have used MMO for years so it should be enough proof that it is a great additive, but none the less, if I knew nothing of these two additives, which one would you say is best for "preventative maintenance" to be run once per year or so in the crank case to keep the varnish/sludge monster & oil pickup gunk far way?
I recently did my 1st MMO OCI in the 5.9L Jeep and I chickened out and did 16oz instead of 32oz and coupled it with some Pennzoil HM 10w30..
Do we have strong opinion or comparison between these two additives for engine oil cleaning/maintenance (and maybe winter starting too)?
