98 V70 Using Oil

My 98 V70 has started to use oil lately after 225,000 km. It is not
leaking as there is no oily spot under it. Seems to go through a litre
of oil every 1,000 to 1,500 km.

Any easy things to check before I place my fate in the hands of a shop?

Thanks.

 

If you are using 0W-30 or 5W-30, try switching to 10W-30. My
'86 Civic Si started to use oil and foul the plugs (and O2
sensor) at about 90k miles, and just going up to 10W-30 solved
the problem completely. The car now has 144k miles on it, and
still needs no oil added between changes.

 

I always use 10W30. Don't want to go heavier than this in the cold
Canadian winter.

 

Check the PCV system (valve, hoses, etc.)

 

I am getting the P0172 code so maybe there is a connection?

Thanks.

 

Here is a little help with the P0172 code:

If I were in Canada, I would use the Esso XD3 0W-30. The 10W-30 is not good
for Canadian winter. The XD3 is a thick 30 weight. If your burning oil, it
will help reduce it some. Oil burning usually means valve seals are shot.
If the 0W-30 does not stop it enough, then try the 0W-40. Both of these
oils can be used year round.

 

Number one is the shop using quality oil or junk oil ?Junk oil will burn off
where as quality oil such as "real"synthetic oil its uniform fractions will
last longer .If you have used cheap oil your rings may be gunned up and
after using a good oil they will work correctly .
