3.9 V6 Oil Capacity
Hi, I am new on this forum.
I actually a 2008Pontiac Montana SV6owner.I would like to post my question here becausethis model has been discontinued in the US andthere has been few activities in related Montana forums.
The newerSV6 and Uplander shares the sameline ofV6 3.9L engine. On my 1st oil change, I was supprised to find the oil capacity is at 3.8 Litres or 4 qts as themanual stated. Othersmaller sedansI had before hold about5 qts.
So the lesser amount of oil in SV6/Uplander gets beat up more with the heat and friction in engine compartment.
I have decided to swicth to Castrol Syntec on my next oil change just to be safe.
Any comments on the low oil capacity? What is the oil capacity in the 3.5 engine?
Thanks in advance
