My 07 Civic has what I consider to be excessive oil consumption. It's always burned oil, not always this much, but it seems to have leveled off after increasing pretty linearly to 1 qt per 2000 miles. At least, I hope it's leveled off. After posting about this issue in the past I decided to switch to Valvoline MaxLife just to see what would happen. I used it as the top-up oil for my last OCI (so probably added 2 quarts of it over 5800-6000 miles) and then filled up with it this time. I'm just 1000 miles into my current OCI but the consumption seems to be with the trend (just added 1/2 quart last week). On the one hand people say that changing brands can cause consumption and it's best to stick with one for a while and see if it improves. On the other hand it's consumed oil over multiple brands and I think this is too much consumption to be caused by a particular oil anyway.
Throwing a wrench into my plans is that the O'Reilly's oil change special this month comes with a Wix filter which makes me want to buy some oil on sale. The Castrol GTX SynBlend looks like a pretty good deal given the sale and I'm tempted to go get some. Now, I'm going to do this regardless because I can always use the GTX in my wife's car (which doesn't have consumption issues, but I'm wondering if I should even bother getting another fill of MaxLife or just get a mini-stash of GTX SynBlend with a few filters and use it in my car too. I could also take this opportunity to try switching from 5w-20 to 5w-30 and see if it helps but GTX SynBlend looks to be a pretty thick oil within its grade in the first place so I don't know.
Is there really any chance at all that the MaxLife could help with consumption if I keep running it, given it hasn't helped already?
