True... But the way I beat my cars... I think Synthetic Royal Purple in my gear box will bo me just fine and be worth the extra coin it cost. I already felt a huge difference when changing gears with the car off it didnt even make a notchy sound as it slid into the gears... Worth it IMO.. (in my opinion)
ended up having to use a 15/16 box end of a wrench for the drain plug. everything else was easy as I was taking out the air filter box anyways to put a new filter in.
I also run Mobil 1 engine oil in my box and I plan on keeping it till it turns rectangle and rev it up to 6 K on shifts... so its worth it for the extra protaction I believe synthetic will provide me.
And never underestimate your owners manual!!!!
Look in the back and it will tell you all the specs for everything!!
Spark plug gap
