How long do you usually run on synthetic oil after the break-in period is finished? Wouldnt it be better to just change the oil filter after the 1st oil change as it'll collect all the excess metal?I usually do mine at a shop.
Change the oil and oil filter after 150-200km.
Do this again after 1000km.
I personally change mine every 1000km until 4000-5000km.
After this change to fully synthetic oil.
No harm comes in changing the oil early or too regularly, but it's important to change the filter after a few 100kms as a new engine will still has metal in it that will run into the oil, best to get it out soon.
Don't run fully synthetic oil until the break-in period is over.
