The oils are so close in viscosity that it doesn't real matter much. If you called the dealer about this, they would tell you that if your vehicle was under warranty, that it wouldn't affect your coverage to use 10w30. The difference is when the second number changes(ie. 10W40 or 20W50)- which determines the protection of a hot engine. The higher the second number the higher the protection- good for higher mileage engines that are driven in extreme conditions. The lower the first number, the better protection during cold starts. Basically, it's a matter of preference when people choose 5W30 or 10W30. No need to change if you're not experiencing any issues. However, it doesn't hurt to change either. Hope this helps.

If your car is running trouble free stay with 5w-30 like it says. My 02 maxima has about 80K miles and i still use 5w-30. There is no real need to switch

They are both good oil for that engine,however since you have that much miles I would use the 10w30 as its a little bit thicker.

you have to be nice utilising the reported 10 W 30 from the manufactor for the vehicle, which will artwork tremendous right down to the -5 levels temps... yet when you have become down that low for quite a few days into weeks, you would opt to make investments in having an engine oil heater put in into your truck.. value about 100 and fifty greenbacks yet fairly well worth it for extremely chilly climates

Myself, I would use the 10w 30. That w means winter,which means that it is easier starting in cold weather, in other words, the 30 weight oil is acting like 10 weight oil so the engine will crank over easier and faster in cold weather for better starting.

10w30,is a heavier oil and protects better,but with that many miles,use high mileage oil,it protects the bearings better,thats what i use.

use the 10. Try 10W-40. That will be even better. You won't hurt it. Try it. 5W is mostly used in high performance cars, like Vettes.

I would only use 5W30 oil for better cranking purposes. 10w30 can be used and will help in hot weather.
