Question about 1998 Mazda 626
Nope, it's not a problem. The numbers relate to the viscosity or slippery'ness (if thats a word) of the oil. The first number (5 or 10) is the viscosity of the oil when you first start the car. 5 is more slippery than 10. The second number (30) is the operating viscosity of the oil after your car has warmed up.
Simply put, in the winter your oil thickens when it cools down so you need smoother oil (5w30) when you start the car.
Winter = 5w30
Summer = 10w30
Hope this helps.
