I have a 98 Dodge Caravan 3.3V6 with 101,000mi. I switched it to synthetic at 70,000 and changed it about every 4,000 using mostly M1. Right now I have Amsoil 10-30 in it with about 3,800mi on it.
When it's idleing hot I get erratic and intermittant lifter tapping. Seems like it's been like this since I switched to syn's. I didn't own it very long before I switched.
I've heard this might be common with these engines but I'm wondering if it has something to do with the thinner oil or maybe gummed up lifters. I dont believe in using cleaning additives. I believe that the engine is being well lubricated but the lifter noise drives me nuts.
Here are my questions:
Should I try switching back to dino oil?
Should I try to get a heaver synthetic (10-40)?
Should I try running a flush through it?
Any comments, Thanks Pete
