I know, stupid question, but I have always paid to change my oil.
Now I'm switching to Mobil 1 since I'm over 55K miles and don't know how many quarts to fill up my engine with.
Also, would 10w/30 be OK or would you give another suggestion? I live in South Florida which is warm and humid almost throughout the year. Maybe 2 weeks with real cold air from the north which doesn't do much at all to the engine I believe.

 

The owners manual details oil pan capacity w/wo a filter change. It should be in the last couple of pages of the manual -- I hope I knew the quantity but then I have a 5th gen and it take 4.25 with filter change.

 

I always put in about 4.75 quarts and check it the next day to see where it's at, then go from there. I use 10w30 Mobil1 synthetic all year round, and never had a problem with it. Although, with 46xxx miles, it seems to eat a little oil between changes, so I hope that's not too big of a deal lol

 

Yes, this seems to be the right amount, 4.75 qts. I switched that day I did the post to Quaker State synthetic, just slightly cheaper than Mobil1, very good quality though.

 

Manual says 4.5 with filter.

 

I've found that 4.5 quarts is not enough. Then, when I switched to the larger Mobil 1 oil filter, it was closer to 5 quarts. The suggestion of putting in 4.5 quarts and then checking the next day after driving a short distance is exactly what I do. You certainly don't want to overfill the engine with motor oil.
