Oil consumption update.
My 2000 V10 Ex was one of those that tended to burn a bit too much oil. I was going thru a quart of oil every 750 miles or so.
I replaced the PCV valve and hose. At the same time I changed oil and went with Pennzoil Platinum 5-30 full synthetic. 2000 miles later I have burned at most half a quart. I checked every 500 miles, at 500 and 1000 oil level had changed so little I didn’t bother to measure the dipstick. At 1500 miles the oil level had gone down a bit. At 2000 miles it went down more. Filled it back with half a quart.
The old PCV valve was pretty nasty looking. I don’t know what had more impact. I believe a high quality oil has less burn off.

That is good to know. Mine uses about a quart every 1000-1500 miles depending on how it is driven-short quick trips vs highway. I am coming up on being due for an oil change and was going to try going away from 5-20 synthetic to 5-30 conventional.

I was using 5-20 semi synthetic previously. I had decided to go up to 5w-30 full synthetic. I went with Pennzoil since many guys on BITOG seem to have good luck with Pennzoil.
When I did this last oil change was when I swapped out the PCV, hose and grommet.

Mine never used oil, but it did rattle on a cold start after a long hot day towing! Sounded like it had no oil for 5 seconds. That was at 20k miles. Since then it only ever got Mobil1 5W30. No more noise on start up.

I think 5w-20 is too thin for our engines. These are not commuter cars. A lot of guys over at BITOG have gotten amazing performance out of pennzoil platinum.( tested by black stone labs).
