What is a good synthetic oil to use in the RSX850i. I have heard that synthetic oil does not break down as bad under hot conditions. I have had great success using it in my Harley. Thanks
It does not look like the 0-40 oil is that expensive especially in gallons. It sure is good for extended change intervals with a TBN of 12.8 compared to Turf Gard at around 7.The 0-40 JD oil is full synthetic. I use it in my RSX 1 because I work here. 2 ik how JD warranty system works. Lol other wise I really like amsoil.
