Hi my name is jean I need help changing the engine oil, I wanna now if I can use syntetic oil and what grade is the right one like 5-30 or 10-30 and also how many quarters needs, I have a mitsubishi endeavor 2004 with 28000 miles THANKS FOR YOUR HELP.

 

synthetic 5-30 is the best one you could use. for low budget, stick w/ regular 5-30. but cant beat synthetic, its the best so far.

 

Some really good oils.

Castrol 0W30 Full Synthetic (no other weights are good)
Mobil 1 EP 5W30 or 10W30
Red Line 5W30 or 10W30

An awesome, cheap, non-synthetic. Chevron Supreme.

 

red line is good to go, gain h.p.'s too.

 

but if u switch to synthetic get a semi blend first cuz you need to get all the old oil out. put mix in or full synthetic that is a cheap price then drive for 500 miles then drain oil and put fresh full synthetic in

 

have you ever try using oil conditioner before??

 

I have a 2004 Endeavor AWD. I just put in Mobil 1 10W-30 extended mileage oil and a Mobil 1 filter, hoping to go with annual oil changes. I've usually gone 6,000 miles between changes. I used Castrol Syntec 5W-50 last oil change, before that was whatever the dealer used (non-synthetic).

I've gone from non-synthetic ("dino") oil to synthetic and back without any flushes on my Chev Lumina APV mini-van and have 172,000 miles in 12 years (currently back to synthetic oil), so an extensive flush is not required (but may be beneficial).

 

actually the oil cap on the engine says 5w20, the manual also says that then 10w30 for extreme weather, im gonna quit messing around with these oil change places and do my own service, gonna start using 5w20 synthetic

 

On my (wife's) 2004 Endeavor I've changed the oil filter at six months on my test of Mobil 1 Extended Life oil. The oil seems to be functioning okay and I've seen worse looking oil on a dipstick. But my wife has put on 10K miles already and the oil is recommended for 15K miles, so might be changing the oil in January. Brrrr.
