To be certain, check your owner's manual. It will list the correct filter size and may even recommend specific brands.
Failing that, you can:
* Look up your vehicle's specifications online: Many parts websites (like AutoZone, Advance Auto Parts, Napa Auto Parts) let you input your vehicle's year, make, and model to find compatible oil filters.
* Check the existing filter: The filter itself likely has a part number printed on it. You can use this number to find a replacement.
Generally, popular and reputable brands like ACDelco (GM's brand), Fram, Purolator, and Wix are all good choices and offer various filter types (conventional, synthetic blend, or full synthetic). Choosing a higher quality filter might offer slightly better filtration and potentially longer life, but the difference may be minimal in normal driving conditions.
Do not simply choose a filter based solely on price; ensure it meets the correct size and specifications for your 1990 Chevy 1500 5.7L. Using the wrong filter can damage your engine.
