Back in October 2021 my son started my 2017 Ram Laramie 4X4 and it started grinding. It had 113k miles on it. Just out of the 100k warranty. Spun bearing. I asked the dealer to talk to their Ram Service Rep to see what they could do. I did the oil changes on it myself. They asked for my service records and I provided all my oil and filter purchase receipts and they covered a new engine for a $1500 deductible. I got lucky. I asked my service adviser at the dealership if there was a warranty. He said no that I'd have to purchase another one. I got the truck back just before Christmas with a new engine. Now with 124k miles it spun another bearing this morning. I was about a mile from home and it started grinding. Here is some interesting info. I had used Rotella every oil change up until 110k miles. At 110k I switched to Amsoil Signature series. So It spun on Amsoil. Not sure if that means anything. My 1st oil change on this new motor was about a month ago and I switched over to Amsoil and it happened again in less than 4k miles on Amsoil. Coincidence or bad luck? I have spoken to a couple mechanic friends of mine and they said it is highly unlikely that the Amsoil caused it. They both think it's more likely to be a machining issue on building the engine. What do you guys think?
