I found Amsoil locally and will now make that once-a-year oil change leap. What is everyone's opinion on using 0w-30 instead of 5w-30? The truck will have 35k at the time of change and is in perfect condition, inside and out.

I think I will also switch to Amsoil transmission, transfer case, and differential fluid at 60k. I just had a 30k transmission flush at Valvoline so the filter will need to come out on the next one.

 

There are several members that run 0w-30, atleast i think i remember members posting about using it.

N3elz comes to mind.

I dont see it being a problem.

 

You will have no problem running 0w30.

I'm running their 5w30 in the engine (Doing 1 year oil changes) w/ their new Ea oil filter. Amsoil ATF in the tranny and Amsoil 80w90 in the rear axle. No issues at all. N3ELZ is running the 0w30 in his engine and doing 1 year oil changes.

BTW could you make a sig with your truck specs, it helps when answering questions.

 

How about now?

 

oh much better

 

whats the next thickest motor oil? Im am using 10w30 right now but mite want to go thicker? less burning oil.

 

There is 10w40, 15w40, 15w50, 20w50, SAE 60, and probably more...

 

i just switched over to amsoil motor oil and was thinking of changing the tranny fluid over now. can i just drain the tranny fluid and refill it ? or do i need to change the filter and flush it first? its only got 2000 miles on the new tranny fluid it was replaced after my accident.

 

Is 0w30 okay for towing a trailer or should I stick to 5w30 for that type of operation?

 

The filter is simply a 100micron screen

Just do a transmission flush (use the forum search its been covered 100x)

 

Yes, they are both 30 weight oils. The 0w30 is only a 0 weight when it's at 0 degrees celcius I believe (same applies for the 5w30 except that it's a 5 weight at that temperature).

 

So is 0w-30 a thicker oil than 5w-30? or is 10w-30 thicker than 5w-30....right now i have mobile 1 5w-30 with only 56k miles on it...and want to change to something thicker longer lasting...

The first number indicates the viscosity of the oil at a cold temperature, while the second number indicates the viscosity at operating temperature.

They are all a 30 weight oil at operating temperature. They only differ when it's cold outside.

Just becuase it's a thicker oil, doesn't mean it will last longer. If you are running mobil 1 5w30, you are good for 5-8k miles. If it's their new "extended performance" mobil 1, then 15k miles. If you want to get a good synthetic oil that will last longer then that, check out amsoil 5w30. Good for 1 year or 25,000 miles. Their 0w30 is good for 1 year or 35,000 miles. Use a high quality filter if you want your present oil to last longer...stay away from fram lol. Use a mobil 1 filter with your mobil 1 synthetic oil.

 

I'm sorry but I don't understand all this stay away from FRAM crap. We've been using FRAM filters for as long as I can remember, and never had a problem. We've only just recently stopped using their oil filters, that's because we started taking them to have that done, which we've found is just as cheap as doing it ourselves and much easier.

 

Yes i use mobile 1 filters with my mobile 1 oil.....ive wanted to try amsoil but havent figured out what exact numbers to order from jusnes...
