So my truck has the service records to back up that fact it was all highway. Based on the wear, and how fast they accumulated the miles per month there is no question.
Having said that, the oil life monitor was indicating 10k oil changes which i am not a fan of. Also right before I bought truck it had one oil change that went 15k, and I opted to drain its last fill at 4k just to clean it up a little.
My question is should I stick with 5k intervals or 6k? Putting the endoscope camera into the oil fill hole shows a nice silver grey cylinder head, cam, and cam caps. No varnish. But I cannot see down into the pistons and ring packs from the oil pan, there is a baffle in place.
Opinions?
