In the old days we had whale brain oil ATF to add.

That stuff was a super lube.

Your owners manual most likely states other alternatives.


Not anymore, I looked in the manual of the 2018 Nissan Altima and it says to only use 0w20, while older models that use practically the same qr25de engine recommended 5w30 in the manual.

Mix away. SAE spec mandates all oils for car engines be miscible without adverse effects.
Just make sure both oils cover the required API/ACEA and/or manufacturer performance level.
For any fun-shuei concerns, check Chinese oil forums.

Take 6.5 ounces of 0W16 and place in a quart container. Add to that 25.5 ounces of XW30.

Send it off to Blackstone.

If the results show a 100C Viscosity in the 20 Grade range, then you will know that one quart of 0W16 grade will thin 4 quarts of 30 grade
down to a 20 grade.

Just make sure both oils (even a blend of 3) cover your own requirement, for what you want in your oils.
(example) I insist on Dexos1 Gen 2 oils, even thou Hyundai and Kia doesn't mandate it. Same with SN Plus, even thou the Korean manuals outline outdated SN.

My current Pennzoil Ultra Platinum does not wear the Dexos 1 Gen 2 badge. Keeps pistons up to 65% cleaner than required by the toughest industry standard. Keeps your engine cleaner than any other gasoline leading synthetic oil.

So I decided to trade Dexos for Best Cleaning Power. Can't have the cake and eat it too, I guess.

Unless you're under warranty and have concerns with that I'd use it just as it is. I had a 1988 Ford Escort for years that recommended 5w30. I used 10w40 in it and when I retired it it had 518K miles on it without a rebuild. Now I own a 1997 Ford, 2002 Ford, 2016 Nissan and run 10w40 in them year around without any problems. Check your owners manual, likely somewhere in it will be a graph showing what weight oils you can use at different temperatures. Some will argue you get better gas mileage with lighter oil but, I am not convinced of that I actually think in some cases the lighter weight oil may cause more friction and increase wear. Since I bought my Nissan Versa about 13 months ago and have tracked approximately 10,500 miles my overall average gas mileage is 47.082 MPG with my worst tank being the first tank I ran through it at 42.345 MPG and my best at 51.167 MPG. My average MPG is 8.082 MPG better than the car's highway EPA rating of 39 MPG and 13.082 MPG better than it's combined rating of 34 MPG.. My worst gas mileage this past winter using the 10w40 and winter blend gasoline was 45.612 MPG. The original factory recommended oil on my '97 is 5w30, on the '02 5w20 (same engine), and 5w30 on the '16.

I would just use the 30 grades as-is. The 5W30 in summer and 10W30 in winter.
An ILSAC 30 grade is not an thick oil and will not cause a problem. Cold winter mornings on a 20 grade is much thicker than a 30 grade at operating temperature.

math says: 0W16 + 5W30 = 2.5W23
Since there are no 2.5W23 specs, I would not mix. grin2

I sometimes mix a left-over quart or so (same viscosity grade but different brand) in my very old cars. Other than that I don't like to risk it with our newer cars especially when it comes to not just different brands but also the weight and possibility of different base oil, additives, detergents, etc. Maybe reduced effectiveness! idk.

Also there has been many discussions that mixing can impact very low temp performance.
I think shannow had some posts or videos about it.

Thanks guys....I was thinking of something like 1 qt. of 0w16....(possibly 1.5).. to 3 or 3.5 qts. of the 30 weight....I'll probably do what Arco says and add a qt. of the 30 wt. at a time to the 20wt....in fact I've done that several times already.

PS SR5: I think you mean to use 5w30 in winter and 10w30 in summer....but maybe you mean your winter (which is my summer) and your summer (which is my winter)..

A lot of the earlier posts were purist--i.e. don't mix weights, don't mix brands, no SN with SN+. I've thrown Dexos Harvest King on top of VWB and nothings blown yet. Don't think your plan would hurt a thing.

I'd sell the oil in question, and use the grade I want or need, and not try and make it. Been there done that and made a little profit in the process.

Who said anything is going to blow, if you mix? Or damage the engine?

All I said is I run the gamit with my GDI pretty strict. No chemistry classes with it. I never suggested anybody or everybody follow my lead.

Very nice and polite way to disagree with different opinions ...
A+++ for that grin2

I just want to say that this thread is why I like BITOG....different opinions from guys who've been there and done that...at the end of the day I think my engine will outlast my desire to own it....but getting opinions from other car (oil) guys is why I'm here....THANKS...
