Can I use synthetic oil in my 1994 Chevrolet Suburban?
Yes. 10W-30 is widely available as a full synthetic, and synthetic is safe (often recommended) for the 1994 Chevrolet Suburban. What matters most is matching the factory viscosity and specification, then changing the oil and filter on schedule.
