Question about my newly purchased 03 SLE!!
The oil filler cap reads 5w 30. The owners manual recommends 10w 30. What gives? :?:

its all subjective... there is no need for 10-30 in the summer time... 5-30 is just as good at 10-30 in warm temperatures, however 5-30 will not get as thick when cold and better for winter months...
The first number refers to the thickness in the cold and the second number refers to the thickness in hot conditions.... but it is all relative

That'* not what I'm refering to. The oil filler cap is suppose to read the recommended viscosity. Why does it say 5w 30??

because that is recommended... if you read deeper into your owners manual i believe is gets more elaborate in one section on viscosity...

blah, i use 0w30 castrol syntec (the green stuff) or amsoil 0w30 when it gets around fall, i think im gonna start using it year round tho instead of going to 10w30 synthetic in the summer, cuz castrol 0w30 is acutally a heavy 30wt in regular weather, i like the best of both worlds 
and id reccomend it to anyone
