I have a 1994 Toyota Paseo. I don't have the factory manual to it so I'm not sure what weight motor oil I should put in the car. And I checked and there is nothing under the hood to specify what type.
Anybody know what weight oil I need I need?

Factory oil used is 5W30 as it produces less friction and allows the engine to gain about 3% better MPG. In real life, 10w40 would be fine, 20W50 best.
I have used Castrol 20W50 for years as my concern is longetivity over a 3% increase of MPG that I would not be able to "feel" at the gas pump. That is 3 extra miles per 100 driven, for me 12 miles potentially extra weekly. I drive my vehicles 200K miles or more and a long trouble free engine life is more important. I've never had an engine experience low oil pressure, burn or leak oil due to following a regular maintenance schedule and I believe my choice of oil.
Multi-grade oils are designed to act like thinner oils in cold weather to help with cold weather starts, and heavier oils under operating conditions to protect against wear. My opinion is that oil is being asked to do the impossible. It is better to use the heavier oil to reduce wear and provide a better barrier between the moving components of the engine. If your starting system is in proper working order, the engine should start in all weather regardless of the oil used, except in Alaska where it probably would not matter anyway if you used the lower viscousity oils.
Diesels are always more difficult to start and therefore oil is less important than a good starter and good batteries. Lower viscosity oils can help some in Alaska in diesels, but most do not shut them down in winter there, they run 24/7.
I implimented and over saw the maintenance of a fleet of 100+ class 8 trucks with the lowest cost per mile, low road down time and longer periods between overhauls than the rest of the 1,800 unit fleet. Regular maintenance and quality oils, filters and inspections are what it takes to get the most out of your vehicle regardless of make, model or year.

Most likely, 10w30. Otherwise, there should be a book at your local auto store to tell you based on the make/model of your car.

i have used 10w 30 in the past but i bought a pontiac grand am and a honda crv and the manuals recommended using 5w 30. i use 5w 30 in my 4 cyl vehicles and 10w 30 in my trucks (ford and chevy)

also matters if youre in a really hot climate or not. If you live in a hot climate, somehting like a 10w40 or even 20w50 is good for the summer.
10w30 is your best bet though.
