Oil Filter: Bosch
Lab: Blackstone (all UOAs)

This is the seventh analysis on this car, newest one is on the right side.

This oil saw one trip home (850 miles each way in a day). My commute is easy with very little stop/go traffic, 20 miles in 30-35 minutes. Have run MC 5w/20 thru my car twice ince it was only 25¢ more/qt then Exxon. Wally World was out of MC so it currenly has Mobil 5000 in it. Blackstone flagged my silicon but changed the air filter last summer so I’m not going to worry about it.

I would think it would be almost impossible to do any better with any oil in this application. It is just such a great engine. I own an Accord but I wish I owned a civic. Great car with great engine and hard to beat for normal use.

Exxon used to cost about 1/2 of MC and now it only 25 cents cheaper. MC has a good reputation so decided to try it.

you've got a sodium problem....may be coolant leak

Looks like it "had" a sodium problem. Could be just residue from the past UOAs. See where the sodium numbers skyrocketed???

The Exxon Superflo uses a sodium detergent.
