Top Off Oil Choices

[Shel_B]

I'm planning a long road trip of about 1,600 miles towards the end of the month. The Camry has M1 EP in the sump. It's possible that I may need / want to top off the oil during the trip. I have two 1/2 quarts in stock that I'd like to use for this purpose. One is M1 10W-40 High Mileage and the other is Castrol Edge EP 5W-30. Which do you think would be a better choice to top off with?

I would stay within the M1 family if possible.

Castrol uses a different DP /AP with a titanium compound.
I would stick with your M1.

I'd go buy a fresh quart of M1 EP if I expected to top up over a long trip. Then it's freshly sealed until i need it.

Due to leaky bottles?

I hear you, but I really want to get rid of these half quarts. I don't have a good place to continue storing them.

I was thinking of using the M1 HM, but for a different reason. Hadn't thought too much about the formulation. I can use the Castrol in sweeties Prius when we do the next oil change.

Another vote for M1 ... thanks for jumping in.

FWIW, I'm not concerned about the bottles leaking. I've had the opened and tightly closed Castrol in my trunk since 9/1/20, and not a drop has leaked or spilled. If I didn't have these 1/2 used quarts hanging around, I'd certainly go with a fresh quart of M1 EP.

Six in one hand half a dozen in the other since it’s just a top off.

Either one would be fine if i didn't have a choice, but having a choice, i'd stick within the sump's current fill family.

Oil is oil. Look at the ratings.

Your car won't know the difference. Use either.

Do you have a lawn mower or something you can use these oils in? They really don't care what you use in them.

Compatibility is a thing that oil has to do. Throw in whatever API.

The VVT system was designed for 5w-30, so that's what I'd pour into it. It'll undoubtedly be fine with a bit of 10w-40, but there's really no reason to favor same brand of the wrong viscosity over a different brand of the correct viscosity.

Agree, will not matter, such a small amount, even Walmart oil will be fine !!
