Mixing 0w30 with full synthetic safe?

[Wolfsburgjohn]

Can I mix 0w30 euro formula with full synthetic for 2016 tiguan??

 

[wpod]

What do you mean ?

 

[Wolfsburgjohn]

I have full synthetic 10 w30 in now can I add a quart of 0w30 to it?

Yes it is safe.

Mixing an API 10w30 with another API 0w30 won't cause an issue.

But VW recommends VW502.00 approved oil regardless of the viscosity you find it in (typically a Xw40). Then again, that's probably only a recommendation and not a requirement.

hopefully, you are aware that your vehicle calls for 5w40 euro oil. or 0w40 euro.

You can, but why would want you to mix an approved (I assume)
oil with some non-approved oil? Oil is cheap, you're engine isn't.

I’m trying to fix the oil consumption. A quart every 300 miles.

How is your PCV?
If you are losing a quart every 300mls, only thing that will prevent consumption is if you pour fresh lava from some active volcano.
You have mechanical problem and you need to address that.

I’m trying to fix an oil consumption problem so I’m just looking for an oil that may be better than what VW gives me. Not sure if it’s a turbo seal or ring problem. At this point I’m not doing any changes just trying to pinpoint.

Which moderate power density engine will have increased wear or destroy itself on a quality synthetic oil with mid 3 hths and a kv100 over 11? Let's get practical here.

I am more curious concerning the 10W30 "full synthetic" already in the sump and .... where does the O.P reside?

Volkswagen so far just shrug their shoulders when I take it in. I’ve had the pcv valve replaced still burning oil.
I’m going to call them today and Ask one more time if they can give me a plan of action before I look for an VW auto mechanic in San Diego.

You’ve lost me sir.

Adding only a quart of an oil within the same grade isn't going to help much, even if it has a somewhat higher HT/HS. As already noted, try a 40-grade with the proper VW approval.

I will say this problem started after taking it to have the oil changed at the VW place. Or maybe Costco gas.

It was a general comment to the forum before you told us about the oil usage.

Did the VW dealer install the 10W30? I am not aware of a spec 10W30 oil for that vehicle. Where did you get the 10W30 and what is it?

Costco gas?? It's not the gasoline. And it's not the dealership unless they broke something.

Yes, 10w 30 is what they put in it. I was told that’s what they use

Well right after the oil change about 400 miles my oil light came on and now here I am.
