What's the difference? I noticed that the oil I use is the blend but there's also full. I'm just curious as to what they mean

 

A blend is a mix of conventional and synthetic.

I run 10w30 Full Synthetic Highmilage in both of my Jeeps

 

Full Synthetic is more expensive but lasts longer.

 

That's what I was thinking. I suppose I could've googled this too lol

 

Full synthetic is all synthetic, and costs more but lasts longer.
Blended is some synthetic, some conventional.
All blends are not 50-50... Be careful.

I run Quaker State Defy, it's blended -- 50% or more synthetic, and high in zinc. Reasonably priced, too.
My Jeep seems to like it.

 

I will have to look at that next time I change oil

 

What's your preferred filter?

 

There are no easy answers on this topic. A "blend" could be 5% synthetic, or 50% synthetic, or whatever. Also, what is meant by synthetic? Used to mean Group IV (PAO) or Group V (ester) basestocks. Now, many "synthetics" are a Group III base, which is simply a very highly refined conventional (dino) oil. Does this make it bad? No, some of these perform quite well. So, a synthetic may be Group III, IV, V, or a blend of any/all of these. You also need to remember that the basestock is only part of the picture; the additive package has just as much or sometimes even more effect on how well the finished product will perform.
