'02 Explorer oil question, 10w-30 ok? calls for 5w-30

[6point0damn2004]

My girlfriend has an '02 Ford Explorer with the 4.0L V6. The manual calls for 5 quarts of 5w-30. I had an S-10 blazer before i had my PSD and I bought the oil to do the next oil change for it ahead of time. I have 5 quarts of Castrol Syntec 10w-30 sitting un-used.

NOW, my question. Would I be ok using the 10w-30 or should I just go get the 5w-30?

It would be nice to be able to use the oil I have sitting around.

Thanks

anybody?

As long as the oil meets the API Certification that Ford calls for, I don't think you will have any issues. With it being synthetic oil, it will probably have close to the same cold pour point as the 5W30 conventional.

I was thinking that it'd be alright too, it's only gonna be for this oil change. The next change I'll do the 5w-30 as called for. I just didnt want to have some oil i could be using just sitting there. Thanks man :thumbs:

Unless you live in an extreme northern place like Alaska or Minnesota, 10w30 should serve you just fine - especially a synthetic! This is especially true as we head into warmer weather.

There will be no noticeable difference in 5w and 10w in warmer weather.

i run 10w in my 02 explorer, no problems after 100,000+ miles
