Hello everyone! New poster here but have been a lurker for over 2 years. Would like some opinions on oil recommendations. Truck in question and a little history:
1994 Chevrolet 1/2 ton 4x4, 5.7l 350 TBI, 3.73 gears. 240,000 miles. I bought the truck with 98,000 mi back in 2001 from the original owner. He always used Pennzoil 10w-30 and so did I until around 200,000. I've used valvoline, QS, and a few others. Truck does not smoke at all and runs great! It does leak a little and I'm sure it burns some. I use the truck to pull my boat in the summer. I change it once a year since it uses oil, I use a good filter, and I only put 4,000 miles a year.
I was given some castrol syntec 10w-30 and used it for the last OC along with my usual WIX filter. Well I pulled my boat the other day, about 3-400 mi total and was 1qt low. 1qt for 2,000 mi is normal. Granted I was running in 3rd turning 2,600-3,000 RPM, 65-75mph, but that seems excessive.
I am thinking about running a 10w-40 high mileage oil from now on. Does that seem like a good choice. What are some of your thoughts and suggestions? Keep in mind it gets hot here and I am using it for a fair amount of hard towing.
Thanks for your time!
