Oil changed, used Amsoil full synthetic. They put 7 qts of 5w30 in. Manual shows 5w20. Is there anything I need to be concerned with?

You should have used Amsoil 0w30 or 0w20. Amsoil also carries the XL 5w20, good Grp III synthetic oil good for 7500 / 6 Months. Use the one you have for 5k. After you run it for 5000 miles, switch to what Ford calls for. Or even better, get an Oil analysis after 2k and see how the oil is holding up in your engine.

 

My truck went its first 160k miles on 10/30. I have since switched to 5/30 even though the manual says 5/20. You will be just fine. I am at 180k miles now

 

Should I take it back and have them put 5w20 in?

Is there any concern for any major issues with 5w30 full synthetic?

 

And last time I went outside in the Canadian prairies in the winter, it was freakin' cold! ( we should know!)

I'm not too sure but isn't there a tolerance issue with the 3V motors. I know the only reason Ford changed over to 5W-20 in the 2V was for mileage reasons. I'm still running 5W-30 in my 2Vers.

 

NO, it will be fine.

 

I don't see why you're so concerned now after the fact.

You should have given that a little thought before the oil change.

Why did you use the wrong oil to begin with?

 

Don't worry about it, It'll be fine, wait until your next oil change and use the correct oil then. Once isn't going to hurt it, twice won't either.

 

I use mobile 1 10w30 I even checked with a ford mechanic and he said it was fine. no worries your good

 

If you read more closely u will se that he isnt the one that put the oil in. He had it done at a shop

 

Using oils thicker than what's recommended may affect the variable cam timing operation.

 

There is no 5w20 Oil in Germany. All Ford uses is 5w30 and I never had any issues. Since I have the normal Ford warranty I guess there must be other reasons why Ford wants you guys to only use 5w20. But if it was availible over here i´m shure I would use it.

 

My '05 4.6, Ford recommends 5W-20. I've ran Mobil 1 5W-30 in it since the first oil change with 0 problems. I read somewhere one time though that with the 5W-30 I lost .6 miles per gallon over the 5W-20, but who knows. I didn't notice anything.

 

5w20 is like a thick water dont use it just stick with 5w30 or 10w30
