Hi all, new to the forum but not new to oil analysis. The subject vehicle is my 2008 Yamaha Rhino (side x side ATV/UTV).
I have owned this vehicle since new and decided to have an oil analysis done after 3,000 miles/200 hours. For the first test at 202 hours I was running Mobile 1 syn 15w-50. The oil test was done with 45 hours on the oil. The results were a viscosity failure with the cSt 100c test reading 10.3 The lab was so puzzled they ran the viscosity test twice!
Okay, second test, same vehicle with 54 hours on Rotella T-6 syn 05w-40. Viscosity cSt 100c 10.5
We have a problem here, the design of the Rhino engine is eating the multi-weight alive! I am now running straight 40wt at the recommendation of the oil lab. Comments?
