Hi Folks, I purchased a 370Z with 10,000 kms on it and want to change the manual trany fluid (6-speed) and rear dif fluid. I talked to a couple dealers and seem to get different opinons on what type and grade of oil to use. Does anyone know what grade and weights of oil can be used and if synthetics are acceptable. Nissan does not list the use of any synthetics in the owner manual, but I want to use the best oil possible and not void my warranty. |
