Engine Mechanical problem
1995 GMC C1500 V8 Four Wheel Drive Automatic

I bought it three months ago.

While towing big loads, this engine starts to burn oil at a large rate Up to 4 qts in 300 miles.

Under normal driving conditions this truck does not burn oil.

Any ideas are welcome, please!

It sounds like your crank case ventilation PCV is not working properly, check your PCV valve,
