Mobil 1 Extended Performance Synthetic 10W30 I do notice a slight lifter tick when the motor is hot but only at idle, bump it even to 850 and it stops. Big difference in mileage. I went from 11.7 avg to 12.6, all things considered...that's covering the cost of the oil right there and then some. Now that's a big *** ram with 37s and 7 inches of lift and a 6450lb curb weight with half a tank.
Thanks, Just finished my oil change and did a minor road test but i went with Mobil 1 regular 10w 30 and the molar filter from wally. And wow just she idle good and just over all it run like a new engine. Now mind you the previous oil was toast and had a crappy filter etc... So it needed it. Will continue to test more Tons of great info in here.
Just built and bored a motor has 0 miles high compression cammed motor I wanna run the best oil but will take ur option. Rather spend the extra money on good oil in the long run. Especially when I want to make horsepower.
