Hey all, OSS here;

Tomorrow I'm picking up a 2000 Blazer 4x4 4 door LT. What are the recommended plugs for this motor, oil type/ capacity, coolant type/capacity?
Is 87 oct recommended, or should I use 91? I've always used 91 in my Cadillac STS.

Thanks!

A few quick searches will give you the answers you seek:
"spark+plug+recommend"
"engine+oil+type+capacity"
"cooling+system+capacity" <-- should give you more than enough info if you read through the whole Dexcool thread which is the first thread in the search results. Capacity is given in a few threads which are aptly named.
"octane"

 

Excellent, thankyou!

 

To the OP, I strongly suggest getting an owner's manual and a service manual.
