Want to use royal purple synthetic oil

Hands down the two best oils on the market are Mobil One full synthetic and Royal Purple also full synthetic. Both offer long engine life with proper 7,500 mile oil changes and do not "break down" under extreme operating conditions.

AMSOIL or Mobil 1 synthetic oils. Either one. AMSOIL claims to be the best but...in order to meet the standards "all" manufacturers of synthetic oils have to have the minimum oil content mixture to achieve the quality standards.

SJ or SL or ILSAC 5W-30 is the manufacturers recommended engine oil.

10w 40 - 20w 50 is good depeding on the mileage. If it is higher mileage, I would use the heavier oil(20w 50). If the engine has been rebuilt or is well maintained, low mileage, use the lower weight oil. Any quality brand will work. If you decide on synthetic, you will be stuck with synthetic! Royal Purple or Lubro Moly makes really great products to give longevity to your engine. It will come with a bigger price tag though.

Synthetic is better and meets all manufacturers warrantys have at it

Royal Purple is compatible with fully synthetic oils so you can change over with no damage to your engine. You can go to the official site and they can give you all the options as far as what your looking for specifically.

I personaly would run amsoil 5w-30 or royal purple 5w-30. Those are a full synthetic and I can tell you from experience they are great. I run Royal Purple in my silverado and Amsoil in my cbr 600rr. Also, from independant studies done on Royal Purple and Amsoil they can go longer between oil changes then most oils. Royal Purple has been tested after driving 22,500 miles and still could be used if you wanted to leave it in the engine. I usually change mine around every 10,000 to 12,000 miles.

use the regular 5 w 30 or 10 w 30. usually that what factory recommends.

depending on what the outside temperature is, usually 5w30 is recomended

can't really go wrong with synthetic oil as long as the grade and weight of the oil is equivelent to what is in there now.

my recamendation is to remove the molding around the gear shifter. look and see if there is any reaon why its tough to move. Also get some lithium lube and spray it around. Move the shifter around and see if there is anything jamming it up. Also, when was the last time you changed the fluid and filter in your transmission. I would recamend using a high end synthetic like royal purple. Maintenance is the key to every problem.

Let me know how this works.
