Have a look at: http://www.moss-europe.co.uk/graphics/uk/instructions/MillersClassicEngineOilsFAQs.pdf and http://www.castrol.com/castrol/sectionbodycopy.do?categoryId=9014096&contentId=7073083

I would think either a fully synthetic or semi-synthetic is fine for your car, as long as it is the correct viscosity (ie SAE 5W-30)

Toyota use a 5-30W semi synthetic but a fully synthetic is fine - but more costly.

'Normal' Oil is Mineral Oil.

Copied from my first link:

"3. What is the difference between a mineral and synthetic Oil?

Both types begin with crude Oil. Mineral Oil is obtained directly from the refining process, whereas synthetic oils are subjected to chemical processing which alters and improves its chemical structure. Synthetic oils therefore have better performance than mineral oils at higher and lower temperatures, but are inherently more expensive."

Non synthetic oils - crudely - are for technically unsophisticated cars and unsuitable for almost any engine made post 1990..

Good for lawnmowers though :-)
