I have a question concerning this oil stuff, when I just freshly got my Nissan primera p11-144, I used mainly 20w-50, but I noticed whenever I'm going uphill the engine gives a crackling sound, I later moved to using 10w-40 grade of oil which reduced the sound and increased fuel economy a bit, when I went for my last service, I couldn't find the 10w-40 variant, as they only had 5w-20 which I decided to settle for. The engine runs very smoothly lately, the crackling sound has completely disappeared. My question now is that: is the 5w-20 too light for my engine, or can I continue using it Someone cited above that his head gasket blew off at high speed because of the light oil he used, would that also happen to my vehicle if I travel at really high speed... Those are my question

eeeeeee:
Virtually every mechanic recommends the use of 20w50 esp Mobil XHP.

This is despite the recommended 5W30/5w20 for most millennium cars (toyotas).

They say the reason is that once the mileage is above 100,000 it is better to use the heavier 20W50.

Please is this true?

What oil should be used in a 1999 toyota camry with 120k,2006 toyota sienna with 100k and 2006 toyota corolla with 90k miles.

Personally, I wouldn't advice anybody staying in Nigeria to use 5w20/30/40 engine oil in their car. My car's engine knocked after using one of those oil and this is my second engine knocking experience.

For one it's too thin and doesn't effectively absorb the heat built up in the engine well enough, add that to our already hot climate.

In both cars, I was driving at a sustained speed of 180km/hr when I suddenly experienced a knocking sound inside the engine. Bearings were found to be worn when the engines were opened. Both happened roughly about a month after servicing.

If you drive mostly within the city and don't speed much then you can go for the 5w20/30/40 engine oil else you might just be looking for trouble.

Car 1 - Honda Civic 2004 EXL(4 Cylinders) - Total 9000 (5w40)
Car 2 - Honda Accord 2008 V6 EX-L - Mobil 1 (5w30)

Does anybody have similar experience as this poster? I'll like to know.

Itulah:


Yes, mine didn't knock though, but it overheat too often especially when I travel. 5W30 is not advisable in Nigeria weather conditions.

20W-50 engine oil is no good for modern engines, regardless of the mileage. It is too thick, and flow to sensitive areas like multivalve cylinders, VVT / VANOS and any other timing adjusters that rely on instant oil pressure will be impeded.

Sludge.
Damaged timing chain tensioners.
Seized timing adjusters / variators.
Poor gas mileage.
Excessive engine wear.
Premature oil pump failure.
Premature turbo bearing failure.
Clogged PCV systems.

These are just some of the results of using 20W-50 engine oil in a modern engine, which has the viscosity of honey or tar.

Some are citing Nigeria's climate as a reason to run 20W-50 in a 2015 Toyota Camry. Rubbish! World climates are taken into account when engines are designed. What is so special about Nigeria? Texas, Arizona, Nevada are hotter than Nigeria will ever be, so is Dubai and tons of other countries. Run the correct oil for your engine, and stop assuming img your Kazeem knows better than the engine manufacturers.

My old Audi S2 I sold with 543,000 miles on the odometer. When it was new and zero miles, the specified engine oil was 5W-30 or 10W-40. At 543,000 miles, the oil spec remained the same, I still used 5W-30.

Those saying their engines "knocked" after using the correct oil, that's nonsense. An engine that is on its last legs, with so much play in the crank main bearings, conrod bearings will run on any old rubbish.

Some unscrupulous dealers and mechanics will actually melt thick grease and fill the engine with the resultant heavy oil, to quieten a rattling and knocking engine, just to sell the car to an unsuspecting buyer. Of course this engine is dead, the moment you drain and replace the oil, it's the end. The destruction is nothing to do with using the correct engine, this was an engine that was already sounding like a bulldozer's diesel engine, that had the symptoms of crank and conrod Bering failure masked by introducing a thicker oil, which would eventually destroy even a healthy engine.

The average Nigerian prefers to accept 20W-50 oil as good for their engines, though deep down, some are aware it's wrong. It's easier to accept the cheaper rubbish than to shell out good money for the correct synthetic oil. These users are also inherently lazy, and couldn't really be bothered to search for the right oil, or import it if they can't find it locally or nationally.

Nice write up as usual Oga Sienna.

I used Castrol 5w40 as against the 0W20 recommended for my car based on a friend's advice that they are within the same temperature range. I will appreciate if I can get someone to confirm what the possible effects will be negatively or positively.
