Go my UOA report today. Thought you guys might be interested.
They say everything looks good. But I noticed sodium levels are a bit high. High sodium can mean coolant leak, but potassium and boron are fine.
Oil is Toyota 5w30. Does anyone know if Toyota 5w30 uses a sodium additive package?
I did drive on the dunes at pismo beach about a month back. Drove through some beach water too. Maybe some salt entered the system some how?
I have now switched to Rotella Gas truck 5w30. So we will see in the next report how that does.
Thanks
