ZedMeister Posted June 23, 2011 Posted June 23, 2011 Ok, as some of you may know I'm starting a 5,500 mile European round trip starting next week, I've bought 4L Castrol 5W/30 fully synthetic to see me through. The Zed has been running on part all her days as far as I'm aware (bought her at 60k), the car has just been serviced with a part synthetic oil change, should I bother changing the oil again for the trip to run it on fully or just top the part up after a few thousand miles whilst out there with the fully? Would it matter either way? Quote
Husky Posted June 23, 2011 Posted June 23, 2011 shouldn't mix oils really, you can create a lovely sludgy mess when the additives react. Quote

Husky Posted June 23, 2011 Posted June 23, 2011 I've been told always to top up with the same oil that's in there. Not sure what the long term effect of not doing it is though sorry. Quote
Steady Zeddy Posted June 23, 2011 Posted June 23, 2011 If you are planning a 5.5K mile round trip then whats the harm in changing the oil and filter to begin with? I personally wouldn't use semi-synth oil in a Zed so best to make the switch now - your engine will thank you for it. BTW - you'll need slightly more than 4 litres for an oil change - somewhere between 4.5 - 4.75 litres to get it to read max on dipstick. Quote

was8v Posted June 23, 2011 Posted June 23, 2011 There is no issue with mixing the oils! Semi-synth itself is a blend of synthetic and mineral If you paid more for the synthetic then you are pouring that money away though. There is little in it these days tho. Z interval is 9k miles so you don't need to change the oil for a long while after you back. Quote
rtbiscuit Posted June 23, 2011 Posted June 23, 2011 just change the oil when the service is due? the car will be happy to do 9k between services be it in the uk or abroad? its just an engine, and its not like its a maserati or ferrari. it is at the end of the day just a nissan. and they build good strong reliable engines. have more faith in your car Quote
