To much oil may cause the oil to foam and the oil pump can't pump foam.

 

I use 4.5 quarts. I've used 5 quarts before and had no problems. I dont think you will have any problems.

 

4 and 1/4 with the filter. Why would you put in more than what is called for?

 

Umm....drain some of the oil....you don't want too much.....and change oil evey 3,750 like the manual says....I use Mobil 1 and change every 3,000.....

 

OT : but polak you should goto the natick, ma meet in august.

That's 208 miles and 3 hours 48 min to drive....I think that's TOO far.......I mean I'd love to go but TOO FAR! (almost posted saying TOO FAT! )

 

You should consider putting in 8 quarts of oil..
no seriously, 4.25.. to much oil is bad... do what the bible says.. i mean the manul...

 

to much oil causes cavitation (forgot the exact term) which results in low oil pressure due to bubbles/foam in the oil.

5 qts might results in more oil being ingested through your intake tract through the crankcase breather area
