it WILL drop your oil a grade. maybe thats what you experienced???? if a 30 is needed, maybe you should start with a 40 and add MMO to that.
i really like adding a pint to 5qts at the last 500 or 1000 miles of a 10k oci....but thats just me
I used the Delo400 15w40/MMO. After 500 miles I drained the oil. Can't say if it did some damage or not but didn't feel comfortable going any further.
Update
The last fill of PP and a fram TG went 8k.
Current fill is PP and a fram ultra. Gonna push it to 10k. Consumption is still lower than before. I will monitor it much more closely this time and report findings.

the first run was with PP and at 4k it was 1/2 a qt low. we added a pint of MMO and pushed it to 5k. next run was PU, at 5k it had used a qt and 9k it had used 1/2 a qt. i added a pint of MMO and changed it at 10k. this run is PU and the car has 6k on it with no consumption yet. is it just me...or could the engine actually be doing better now than before with the extended drains??
Sounds like you have saved her neglected engine. Nice job! I've had the same consumption pattern when switching an older vehicle to synthetic...initially uses some, which tapers off and goes to 0 or close to 0 consumption.
