Mike thank you for that comprehensive advice,i will follow it and do it bit by bit.
My truck has done 176000 km and the last owner who wasn't the first owner changed oil every 10k.
My original question about which oil can you advise please 5-30 or 15-40 ?the mechanic also advised against a engine flush with fear of releasing crap into and around the motor.
I am in New Zealand otherwise Id give you a bell.cheers

If using regular oil, change it every 3000 miles, synthetic can go to 5000 miles.
5/30 or 10/30 for winter use and 15/40 to 20/50 for summers.
