Default Oil consumption

Hey im new here i was just wondering if there is a solution for this. My car is burning oil within 1500 miles it burned out almost 1.5qts its seeming to burn more frequently too. Car runs really good i bought it with 132,000+ now it has 145,000+. When i bought it was not burning anything its a 1998 honda accord ex 4cyl coupe. For oil i use castrol edge full synthetic with lucas and fram ultra filter. Not sure but could the lucas be causing sludge build up?

Also a/c dont work could that possibly play a part because of it not working maybe not cooling the engine down correctly? Only saying that because i changed spark plugs and looked like they were starting to turn white at tip and i have a book that diagnoses them and it said it could have something to do with sticking valves and insufficient engine cooling etc. Idk much about cars any advice or solution would be much appreciated.

The Lucas is snake oil anyway so you can lose that and save yourself some money.

Regarding your oil consumption, a couple of comments:
  • A quart every 1,500 miles is really not all that bad, especially for a car with over 100,000 miles. That said, some cars easily make it to the quarter of a million mile mark and can still go an entire oil change without consuming a quart.
  • If I read your post correctly, it sounds like the accelerated oil consumption is a relatively recent phenomena, if so, it is not at all unusual for a gummed up PCV valve to cause a sudden rise in consumption. The valve is cheap and relatively easy to replace, you might want to give that a try.

No, a bad PCV valve will not throw a code; it is considered a normal maintenance item.

Marvel Mystery Oil (aka. MMO) is just as much snake oil as Lucas. If you need a light oil, then use light oil, no need to add light oil with a witch's brew of crap in it.

Another thougth; is your car one of the models which require periodic valve adjustments? If so then it might be time to get that done.

Why 10W-30? Doesn't your engine call for 5W-30? FWIW, in the world of Synthetic oil, 0W-30 is better than 5W-30 which is better than 10W-30; the lower the "W" number the faster oil pumps up out of your oil pan and into your engine following a cold start, even if said "cold start" is out in the desert where the ambient temperatures are above one-hundred.

Regarding the MMO, messing with it will NOT change your oil consumption one bit; it will just drain your wallet some.

I usually use 10w 30 in summer and 5w 30 in winter.

If the PCV is old, replace it; I've seen plenty which would rattle and yet were still bad.
