Oil filter light on 2009 g37 came on and won't go out.

check to see if you have a water leak into the sump
change over to diesel oil and change the oil filter every month for at least 6 months
diesel oil is the same as petrol engine oil but with a heavier detergent additive so it will clean out the sludge and deposit it in the filter

first you abuse the engine but cange the oil whit 15w40 i know is for diesel engine but that oil have quimical to clean engine and make two othrer oil changes every 500 milles and see what coin on good luck

drain the oil and use a engine flush oil , follow the instructions to the letter ,may have to repeat after next oil change, do them every 3000 miles including the filter, nothing beats good maintainance 15k what was you thinking !

Here's some trouble symbols.

My g37 will start up but after 5mins of warming up it will just shutoff, now my keyless remote won't even open the car or start it unless its in the key charging port.... Any suggestions what this might be? Also went to mechanic and no codes popped up

I am not sure I know what you mean. Are you talking about when you are braking the pedal pulsates?

This is spotting from the plastic they use to protect the paint!!! Ha when they apply the plastic it sometimes has air trapped under plastic a bit like a bubble under tape, the sun bakes the gases out of the plastic and it stains the darker painted cars. Good luck and tell them this when they try to blow u off.

Heated or not, condensation in the upper cylinders may have caused some rust to form on the piston rings and other steel parts. These minute rust particles can be highly abrasive and cause damage.

To minimize this, remove the spark plugs and spray into the holes a small amount of high quality motor oil such as Mobil1 5w-30. Do not replace the spark plugs, then with the ignition disabled, crank the engine for 2 seconds, pause for 5 seconds; crank for 3 seconds pause for 5 seconds; and crank for 5 seconds. This will help pre-lubricate surfaces that have become "dry."

Then replace spark plugs and you are ready to go. Keep speeds below 10 mph if tires have developed flat spots, until they are gently warmed up and rounded out. Drive the car for several hours to flush out any pooled contaminant moisture, acid, or particles, Have the oil and filter changed before they can cause any damage.

Note: Removing the spark plugs is an involved procedure. Do a search on "changing spark plugs on g37" to view the steps.

go to status, maitenance and then set the next oil change schedule to 37500 mile from what you have in the Dem.

Please change the oil now at the Nissan garage and watch the vehicle closely.

$100 is not so much like getting your car totally knocked.

Good luck and rate this solution/ suggestion.
