Sir , I rather be safe than to be sorry... I will rather follow owners manual at all times.. The car manufacture are the ones that make the engine , so they are in a position to know better... I will not gamble with my hard earn money ... . Another example is 2010 Camry.....

Go back to the original question. This merry go round is uncalled for.

Where is motorguru sef?

GAZZUZZ:


I respectfully disagree with you sir. 20w50 will only give poor lubrication on cold start and decrease efficiency of the vvti system, if engine oil is changed say every 2,000 miles on mineral 20w50 engine will remain unaffected and can switch back and forth as he wishes.

Dear motor Guru,

My MdX 2007 sometimes shows check transmission mostly when I am reversing and there will be a flashing of the D- sign on the dash.

I check the transmission fluid and is a little low at the bottom of the lower dip sign instead of in between. So I asked a friend for his scanner and did a quick scan and it showed a code about transmission range switch open or short circuited.

Although when this error shows up, the car still drives smoothly without any slip, noise or drag. I don't just like to see any yellow sign on my dash.
Please what can I do to fix this.
Thanks

I got a naija used car but previous owner uses 20w-50 but changes often
As directed, i opened the engine oil cover to ascertain the level of Sludge in the engine (i dont know if it works this way) however find attached the pic.

I intend to use total quartz 9000 5w-40 for some time instead of straight 5w-30 due to what has been said.
Please recommend

Your candid advice is needed here. Which would you advice a first time user between 2006 and above Honda civic, City, and Toyota corrola.
In terms of Realiablity, comfort, and affordability

Budget is 1.5 to 1.8

Hey Boss,

I'll like to know the price range of the 02 sensor because my car is consuming much fuel, got the code 1 fixed and the panel beater said I should not worry about the code 2 but I noticed that I use more fuel than usual.

Please advise.

RealDannie:


Morning Boss,

Took it for repair last week and they claimed that code 1 has been fixed that everything is fine but I noticed that I used more fuel during the week and went for another scan only for me to get about 8 error codes including the previous ones.

Please help

MotorGuru:


This is very tricky.

The pic shown is a huge precursor to engine sludge.
Before you perform engine oil change from the 20w50, get a mechanic to open the valve cover for inspection.

if sludge is present, please stick to the 20w50

if no sludge, try mineral (or syntheitc blend ) of the 5w40, and monitor oil consumption of engine

if no consumption present, move up to 5w-30

kingreign:





Don't try this, continue using your 20W50, if you diesel flush it, it will start smoking and ultimately get knocked.

MotorGuru:


when last did you perform a tuneup( spearkplug change, air filter etc)

also when scanning , check and post short term fuel trims(STFT) and long term fuel trims(LTFT) here

MotorGuru:


Now this is worrysome.


clear codes, and drive vehicle till codes come up again

then rescan

I went to buy a car as low as 300k.... I saw some clean Mitsubishi products as low as 200k,NY mechanic said the products are sh!ts.. I have to listen to him. Saw a Peugeot 306 of 350k,my mechanic said its old model... What do u guys suggest

MotorGuru:


what vehicle is this sir?

MotorGuru:



are you experiencing very hard shifting?

tech that will clean ups...then you are good to go

MotorGuru:


Sorry sir for the predicament.

I will seriously advise that you take the car for a diagnostic scan. It is very likely you have a defective ECU/ brainbox. This is a common issue with 2001 to 2003 Toyota rav4s. Driving the car like that will ultimately damage the gearbox mechanically. If after scanning, you have transmission related codes, then you will have to replace the brain box or repair it. Pls stop driving the car for now.

Dear MotorGuru,


My issue has to do with the transmission of a 2001 Rav4 that I just got. After purchase, I had my mechanic drain the transmission fluid inside and replace with Toyota Type T-IV. I decided to take it with me on the family Christmas trip and noticed that it wouldn't go beyond gear 3 (80km/hr at 3100rpm). Even when I fire up to 4000rpm, it still wouldn't engage gear 4. All through the trip, I left the speed at 80km/hr (3100rpm).

Apart from that issue, I noticed that the Reverse gear when engaged would sometimes give noticeable jerks and the accelerator depressed. Other times, it moves fine.

I'd like your opinion on what's going on and how to rectify same. Many thanks.

MotorGuru:


I think you are interested in something that will serve you well. unfortunately the budget proposed may not give you your heart desire.
i would advise you save up some more and get something more reliable.

GAZZUZZ:


scan and replace knock sensor
