A. Engines with hydraulic lifters require 5W 40 oil (mineral or synthetic). Note Also: The engines with hydraulic lifters have a new camshaft with different timing than engines that do not have the hydraulic lifters. The hydraulic lifter camshaft timing is: Intake: opens 20 before TDC. Closes 47 after BDC. Exhaust: opens 51 before BDC.
