If it is the 4.3 liter engine and you have drained all the oil out of the engine oil pan and you have replaced the old oil filter with a new oil filter, then you need to add 5 quarts of engine oil to get the proper level in your engine.
5w30
On the oil cap it says "5 W 30".
A 2001 Chevrolet Trailblazer uses a STP Extended Life Oil Filter
Yes
The oil sending unit on a 2001 Chevy Blazer is just above the oil filter. It is actually located on the diagonal to the oil filter to the upper left.

trans or oil? oil is in front left. i dont think the 98 blazer has a trans dipstick. Instead, there is a bolt on the side of the trans.
10w30 is what I would recommend for a 8 year old engine.
This sensor is at top rear of engine, next to distributor.
