does removeing oil pan cover help oil temp?

I have searched but can not find the answer, does leaving off the plastic oil pan cover help the oil run cooler? The one that you must remove to change the oil. Thanks

It might help a little bit, but the first time you catch a rock or other road debris up into the engine compartment you may wish you had not removed the shield.

Replace it with the ZSpeed metal one. It's got cooling vents (although it's hard to say if they do anything), and it's much tougher than the stock plastic one.

No noticeable difference. My oil pan cover, nismo version, fell off for the third time now and this time I wasn't able to retrieve it. I have the Zspeed metal one on order, hopefully it arrives soon. But for the last few weeks I have not seen any change from the norm.

I still can't believe Nissan charges 900 for the stupid little piece of plastic.

Are you serious? That thing is held on with 16 fasteners (or so) and it has fallen off 3 times???

Their are an awful lot of those screws alright holding on the cover. If it fell off, something is wrong.

Thanks guys, that is what I thought, but after the dealer changed the oil I noticed that the temp was running 15 degrees hotter so I called them back and asked what kind of oil they put in and they said penzoil semi synthetic so I will be running Red Line from now on. He said not to worry as long as it stays below 260. But that seems kind of high to me.

Missing under piece to bumper/front lip?

panel fell off... what's the purpose?

It has fallen off for a number of people. Some due to debris on the road some just for no reason just speed.

Usually its only the smaller plastic strip part 75895 which is held on only by a few pins. Which is only a few hundred dollars. The larger part 74811 usually only come off partially and gets damaged.

For me the first time I didn't even realize that the small was just missing when i did my first oil change and got a replacement from the dealer. The second time the I was able to pull over to the highway shoulder before the smaller piece came off completely but it had ripped the bigger piece while it was dragging. It took some effort to get it replaced because they assumed I hit something but there was no sign of any impacts on the under body and they replaced the whole thing. Finally not too long ago the smaller piece fell off partially again but there was no area to pull off to the side and eventually flew off. So I have on order a new aluminium which will not come off and is less then half the price of the Nissan plastic.

Whoa. That's crazy.

without the lower shroud i read that the front bumper can not handle the air and starts deforming at speed.

and yah, tighten those bolts snug tight. i lost a few screws on my G when i let my dealer do the first 2 free oil change while new.

was a big mistake. (they gave me replacements).

Another good point. It keeps the bottom of the bumper in place. Plus, the car was designed to be run with it on. With it off, couldn't air force its way up into the engine compartment from underneath and slow airflow through the radiator?

more likely it would help engine venting, but at the expense of higher speed stability due to the high pressure zone in the engine bay being able to easily vent into the low pressure zone (produced from the front aero spoiler), increasing front end lift.
