When did Castrol GTX become High Sodium?

[bennybigb]

I have some SJ and SL Castrol GTX 10-40 that I am looking to blend with 5-20 to use in my early 90's toyota car.

I assume SJ/SL GTX is low sodium, so I am concerned about mixing it with new High Sodium GTX. What would be a good mixing oil for this older GTX oil? I am thinking a Warren Oil like Peak or Pro Line. What do you guys think?

You are looking into this too hard. Both are compatible especially for what application you intend on using this oil for.

+1 you have an almost 20 year old car. Sodium wont make a difference. If you don't feel comfortable putting in your car just use it in your lawn mower and buy something else

What are people`s fear of sodium in the oil?

OK Thanks.

I didn't think you were supposed to mix high sodium oil with classic add pack oil.

Also, just to add, PEAK and Proline have sodium as well. Sodium (the type they use) is actually an outstanding corrosion inhibitor. We think sodium and rust (at least I do) but that couldn't be farther from the truth in this case.

How do you know that info about Peak?

I do not fear it. I just prefer if the cost to me are the same to use a motor oil that uses Calcium.

Okay, fair enough. But what is the difference ? J/C

I am just biased against Na in motor oil when compared to Ca. It is just a personal preference nothing more.

Okay. I understand.

If you do used oil analysis, the sodium in the oil can mask head gasket problems. That's my main reason for avoiding it.
