I have a 2017 1500 5.7 that’s had nothing but Amsoil SS 0W-20. Purrs like a kitten. I have done multiple used oil analysis on all my family’s vehicles. They all use SS OW-20 and the analysis come back with very positive results. I will never use anything other than Amsoil.
At 156k after cam/lifter replaced I started doing DIY Amsoil changes. At 255k I put in a crate engine. If Amsoil made a difference it got the bottom half of the engine to 250k miles from 156k so about 13? oil changes. I think the cost difference is minimal so yes, I think it was worth it. Delaying $10k for new engine is the goal.
I use Castrol as it’s the OEM product and is cheap if you buy direct from Ford.
Mopar oil filter, amsoil 0w20, don’t over torque filter housing.
My more modern VW runs Castrol EDGE OE 5W-40 full synthetic. That's what my VW dealer in Utah fills cars with.
Was using motorcraft, switched over to Amsoil. Cost is the same maybe a couple dollars more.
I use Castrol EDGE Supercar 5w50. Oil change 7000km ????. no problems! Mileage 150 000km . Car from 2014!!
300.000km - oil: Castrol Edge 5W-30 and a new vortex breather - without oil consumption
315.000km - oil: fuchs titan 5W-30 and the old vortex breather - around 1L oil consumption
330.000km - oil: mannol 5W-30 and the old vortex breather - around 1L oil consumption
345.000km - oil: eneos 5W-30 and a filter type breather - without oil consumption
I'm running Castrol EDGE 0W-40 A3/B4 right now, but feel there is more startup noise than when using Mobil 1 FS 0W-40 European Formula.
I have used Amsoil, but I feel as if my motor makes a funny noise with that in it.
