Mixing Mobil 1 Oils together a bad idea?

[Ozer]

Not another "Which Oil" thread.

I do my own changes around 6k-7k miles with Mobil 1 filter and usually go with what Mobil 1 is on sale/deal at the time.

Can i mix 2qt of 0W-20 extended performance with 5qt of Mobil 1 0W-20 Advance fuel economy + 1Qt of Advance fuel economy i have left over to get 8Qt for my next change?

 

I would never mix different brands or weights but wasnt sure about same brand and weight with different "platforms"?

[diyer2]

Not a problem IMO.

 

[Grumpy Bear]

Yes. 

[diyer2]

I have mixed the same brand oil and weight.

Used left over dino oil to replace burned off semi syn and vise-versa.

Have mixed them for oil changes also.

My short 3 K mile changes may be a benefit doing this.

You’re good to go.

Don't forget to do the Mobil 1 rebates if that's what you use, makes your oil changes even cheaper.

[Cheverado]

Been there done that(or something similar)

[mookdoc6]

Absolutely!  Keep within GM Dexos Spec...NO issues!

Mixing isn't an issue with the same brand oil like what you are doing. 

 

Even mixing the same brand with like a qt of 0w-20 and maybe a 5qt container of 5w-30 isn't going to cause any problems.

Looks like Ozer supplied you with links already. But for me I used to wait for the 5 gallon buckets of Delvac 15w-40 to go on sale at Autozone. I'd then buy two and submit the rebates for them. After sale price and rebates I was almost getting 5 gallons of oil free, especially since they upped the rebate to $35 for a 5 gallon bucket.

Very nice!!! I gotta remember this. Thanks

I've done pretty much what you have done plenty of times. I've mixed 5W-20 and 0W-20 and really made no difference.

This rebate program runs about the same time every year. In a week or two you will start seeing auto part stores do similar rebates but i usually do amazon or walmart since they are the first ones to start the sale.
