While poking around under the hood of my TCH, realizing I don't have a clue as to what most of this stuff is, I identified the dip stick (kinda felt like a dipstick myself) and oil cap. The oil cap (and manual) recommends SAE 5W-20 or 0W-20. No, I did not mis-type: zeroW-20. I've never heard of this. It's gotta be as runny as vegitable oil. And then the thought occured to me: do I go with conventional or synthetic? All that starting and stopping's gotta be brutal on the oil.

Anybody have a suggestion as to what I should put into this car to maximize life, liberty and the pursuit of happiness?

Thanks.
