Noticed a huge difference in engine noise after switching oil viscosities
Honestly, I ran 10W-30 in my 2004 Silverado for like 5 years and just dealt with the lifter tick. Switched to 5W-40 last month after a buddy at the shop in Nashville told me to try it, and the ticking is almost gone now. Anyone else had a similar result from just changing oil weight?

Yeah @the_viola is right, thicker oil can really help with that. I ran 10W-30 in my old Silverado for years and the lifter tick drove me nuts. Switched to Rotella T6 5W-40 and it damn near disappeared after about a week of driving. That extra viscosity seems to cushion the lifters just enough to quiet them down. Did you notice any difference in cold starts though?

How many miles were on that Silverado when you switched? Did you notice any leaks from the thicker oil?
