Just wondering what everybody runs as far as engine oil and filter.
I run a wix 51773 oversize filter. Its a bit tight getting it in there but it fits and works great. My oil of choice is castrol edge, 10w30 full syn. This allows me to extend my changes out to 5000 miles, and it comes out still honey color just like when i put it in.
What do You use???

 

Purolator filter and Mobile 1 synthetic 10w30.

x2, i use the rotella t, also ive been wondering what i should use during the winter, the 15w 40 is too thick

 

They are the same thickness cold. Only variation is when they get hot.

Motor oil with 2 numbers "5w30,10w30,10w40,20w50, and so on" means that it is a multigrade oil. As with strait weight oil "30w, 40w, 50w,etc." multigrade oil gets thinner when heated and thicker when cooled. But multigrade oil has additives that try to reduce the amount of thinning and thickening, therefor keeping the oil closer to a preferred thickness more capable of lubricating your engine over a greater range of temperatures. The first number represents the thickness of the oil at a cooler temperature. If you are working with 10w30. That means the oil should be the same viscosity at strait 10w oil at the same temperature. The second number represents the thickness of the oil at a higher temperature. Again, using 10w30 as an example, would mean that this oil should have the same thickness "hot" as a strait 30w would have "hot". As you can see, a multigrade oil in a way acts like two different "weight" oils in one.

 

Fram tough guard and Valvoline 5w30, fresh today before cold fall/winter weather sets in.
