alot of you have been following my build thread on here

i am coming up on 315 000 kms and i want to change the oil on that mark

last service was just before 310 000 kms and i changed from Honda FEO 10w30 to Honda FEO ULTRA 5w30 Synthetic - using a J's Racing Sump Plug

ever since i changed to FEO Ultra the car has been using a little bit of oil each week - every time i check it it needs a small drink - but when i was running normal FEO it never moved

i think the car feels just a touch rougher with the FEO Ultra in it as well - but that could be just my mind playing tricks on me

so should i go back to normal FEO? or stick with FEO Ultra?

also would i benefit from using some supermarket oil during the change to give the system a flush?
