I drive a 2004 toyota rav4.last serviced on Sep. 2016 wt Mobil1. I observed recently that the oil pressure indicator flickers whenever engine is driven for abt 2-3hrs during breaking. I have changed the oil switch & oil filter as advised by mechanic but to no avail. I'm so worried now. Experts in the house pls come to my aid!!!

If its wat I'm thinking, it shouldn't be more than a failing oil pump.

How about a sludged up engine with clogged pick up tube.

Op remove the cap of the oil fill and take a picture, trying to see how black the inner part of the cap is.

Worst case scenario will be to drop the pan and look at you oil pick up screen

U still need to confirm further if you are a dealing with low oil pressure issue which is directly an engine issue or u are dealing with an intermittent electrical issue .
Get mechanic workshop that has oil pressure gauge equipment ,simulate the condition that cause the oil light flickering and check the oil pressure value with the oil pressure gauge to actually know if the oil pressure is low @ certain condition.
This will help you narrow down this issue and check if there is any odd noice when running the engine especially @ the flickering oil light condition.

The conditions are clear,When Hot!! that rules out any electrical issues.

I'm 100per sure that engine rattles when revved at low speeds.

Electrical resistance changes with temperature especially if there are some frail wire that is already losing connectivity ,so electrical issue cannot be rule out cos i have got similar experience before .Also t is easier for the op to start checking the wiring first before start opening the engine up to rule out that possibilities .
But the op can also confirm if there is any rattling noice at start up.

A pic of oil cap will let you know if sludge loosen by mobli could be the problem or frot from coolant.

He said when braking which could also be low oil level from oil leak, last oil change done 3 month ago enough time to leak + burn through oil

1. FAILING OIL PUMP..

2. FAKE WRONG OR BADLY INSTALLED OIL FILTER

. CHANGE THE OIL FILTER AND MAKE SURE U GET AN ORIGINAL ONE .. LOTS OF FAKES OUT THERE...ALSO FLUSH THE OIL JUST INCASE OF A CLOG..ASK UR MEC FOR AN OIL FLUSH..

IF OIL SWITCH LIGHT CONTINUES TO FLICKER... PARK THE CAR AND DNT DRIVE IT AGAIN UNTIL U CHANGE THE OIL PUMP... IF U DNT DO THIS SOON THEN GET READY TO CHANGE UR ENGINE METALS OR REBUILD UR ENGINE OR WORST CASE REPLACE IT .. COS IT WILL KNOCK UR ENGINE FASTER THAN FLASH..

WHY WOULD U REV THE CAR IN THE FIRST PLACE.. DUDE THE LLIL FILCKERING UR TALKING ABOUT IS UR METAL BEARINGS ... THEY ARE RUBBING AGAINST EACH OTHER CAUSE UR OIL SUPPLY IS LOW... GET A GOOD MEC AND CHANGE THE OIL PUMP ASAP...

Many thanks to experts in the house for the advice. The vehicle was driven to the mechanic workshop, oil pan was removed, oil filter sieve blocked with dirts/ particles. It was thoroughly cleaned with petrol & engine was serviced with new oil & original oil filter. Car ran smoothly without any hassles after driving for about 100km.

Unfortunately you are not out of the woods yet, did you find metal shavings in the pickup screen or thick sludge?

If it was metal shavings, you have major engine wear, which will eventually result in more sever damage in the near future. If it was sludge, then a change in the oil change intervals and type of engine oil might slow down the untimely death of the engine.
In either case, you still need to pay more attention to future maintenance procedures on your engine.

@OP, just curious....have you always been using mob 1?
i had a similar issue on a rav when i switched to mob 1, after using the wrong oil [20w 50] for the ist 3yrs of its life in naija.
so am guessing the mob 1 knocked off dirt/sludge that was presently in the engine, and it started blocking the oil pick up line intermittently when the engine was driven for abt 2hrs/100 miles too

Metal shavings were found on the oil pick-up screen although very very few. What preventative maintenance is recommended pls.? I don't want to lose this engine so soon....Cc GAZZUZ. ..
