I think the 10-14K mile oil change intervals that the owner followed post-warranty, even with an Amsoil product, are too extreme for this Nissan built motor. I don't understand that plan.
I think because he uses Amsoil he wants to get his money "worth", even if it's bad for his engine.I think the 10-14K mile oil change intervals that the owner followed post-warranty, even with an Amsoil product, are too extreme for this Nissan built motor. I don't understand that plan.
I wholeheartedly agree.I think because he uses Amsoil he wants to get his money "worth"
I would not extend OCI on a Nissan engine. 5k is ideal with a reasonably priced oil (anywhere from $20 to $25 5-quart jug) and a proper filter.
When you change the oil, you only get 90-95% of the old oil out.
My thoughts exactly.What's it taste like?
It's a silly question, but no more so than looking at the color of engine oil and expecting to know anything about it's condition.
I'll give the OP a pass since he's new here.
The rest of you ought to know better.
The way I read this is that this current fill isn't Amsoil and is whatever synthetic the shop put in. Correct me if I’m wrong…2017 qx60

Mostly Amsoil SS, most recent one is synthetic from a shop

I'm having flashbacks to when I asked this same question about an OCI on my truck's engine with Euro 0W40 Castrol. I was ridden like Ole Seabiscuit by a few members here.This is from a dip stick after 130miles since the oil change. Is it darker than it should be?

I'm new too but was going to say the color is irrelevant.....What's it taste like?

That can happen a couple ways. #1 went too long on last oci. #2 the new oil is a good "cleaning oil" (like most today)This is from a dip stick after 130miles since the oil change. Is it darker than it should be?

Oils are not good cleaners, FWIW. The main advertised trait is keeping things clean. Cleaning up existing deposits is a whole other animal.That can happen a couple ways. #1 went too long on last oci. #2 the new oil is a good "cleaning oil" (like most today)
#3 not all old oil removed. That used to happen whenever I went from another oil to Amsoil the first 1 to 2 oci.
Some of his last OCI's were with Amsoil SS and this is an oil that is supposed to be a Long drain oil. If this Amsoil SS is a long drain oil then it should keep things clean. Then again I do not have a DI Vehicle and we do not know the OP's driving habits.I'm having flashbacks to when I asked this same question about an OCI on my truck's engine with Euro 0W40 Castrol.

It looks as if the current OCI is cleaning up what past OCI did not clean.
yes.... Its likely more about how long in service and how much gets left behind. We been using extraction pumps for years.Oils are not good cleaners, FWIW. The main advertised trait is keeping things clean. Cleaning up existing deposits is a whole other animal.
