I'd imagine the 3750 would be for conventional as well. If I were to stick to the 3750 interval, I don't think I'd use synthetic...but I'm really cheap. I would at least use a good name brand...no "house" brand stuff.
Since the other intervals are programmed in there, there must be reasons. Maybe the stealership would know more.

 

Hi All. As a new (second hand) MYO8 Outlander owner these forums are great. Here in Australia, the designated service interval is 15,000kms (approx 9,300miles)/12 months. Most of our driving is as mum's taxi. I wonder whether we should at least be changing oil and filter at approx the 7,500km mark and then put it in at the dealer for the 15,000km service as this is a requirement to keep the premium roadside assist package for the life of the warranty (5yrs)?

 

Hi fellow aussie!

I always do both out Mitsu's (09 Outie & 02 Magna Ralliart) at 7500km - ive always felt that 15000km is just too long, best medicine for a car is regular servicing

 

Thanks Ricbec. DO you just do oil and filter at 7500kms? Do you do it yourself? Those quick oil drain valves look the go. Any idea if they're avail in Oz?

 

na mate, i take it into Mitsu each time, i usually get other stuff done at the same time.....like tyre rotations and engine bay washes....things like that
