is it will be fine?

Here is a deal. My father has 06 Nissan Frontier with 2.5 L engine. It has 91k miles on the clock. He doesn't drive it hard, and mostly highway miles. For couple years his roundtrip to work was 80 miles a day. This truck has some moderate loads sometimes, like furniture, motorcycle,lawn mover, drywall, tiles... So it's not driven very hard. He claims he used syntech oil from start,he got it brand new. His OCIs are 10k miles. I'm doing changes for last couple years. It usually gets whatever syntec oil is on sale. Usually Castrol,M1,Penzoil,Valvoline. Month ago I seafomed it 3-way, before change, put in PU and can of Moly. Is he will be fine with 10k ocis? And I was thinking switching him to HM syntech like M1. Is it time? I'm not sure is there any varnish or other deposits,can't see through long filler hole. Will takse closer look during spark plugs change out.

I assume by "syntech" you mean "synthetic?" and not castrol syntech?

 

[zyxelenator]

yes, you got it.

 

[zyxelenator]

yes, you got it.

No problem. Any synthetic will be fine for 10k miles OCI as long as his drives are mostly long distance of more than 20 miles. No need to switch to HM, my LS400 has more than 250k miles and E430 is almost 130k miles and both still use non-HM oil.

Nothing wrong with what you are doing.

No need for high mileage oil unless you are using some oil between changes.
Even then, if the oil use is minor, it may be cheaper to use a little oil than switching to H.M. oil which costs more.

During work days, he drives more than 20 miles a day for sure. Weekend- probably same, but plenty of short trips to the stores around, plus maybe some hwy trips around 15 miles one way.

sounds like the typical life of an automobile/light truck--you can go 10K miles, but not one mile furthur IMO
