Good one op

Pls my car Corolla 2012 has 0w20 as an engine oil spec
And manufacturer wrote 5w20 if the former is not readily available
Someone told me its same with 20w50

Pls how true and any advice.

AutoTechNG:


You may use 0w20 in place of 5w20.

But to use 20w50 in place of the engine oil specified is to ask for trouble!

If you want more proof, you could spend some time perusing this thread: https://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=2576123 entitled "Are 5w20 & 0w20 Interchangeable?"

It is scientifically impossible for 5w20 to be interchangeable with 0w20 and at the same time the same as 20w50!

For OCI's of 10k miles or longer, synthetic oil is needed in many engines. Mercedes learned that lesson with a multi-million dollars lawsuit early 2000's:

"U.S. District Judge Franklin S. VanAntwerpen has approved a settlement worth more than $32 million in a class action suit against Mercedes Benz brought by owners of cars manufactured from 1998 to 2001 who claimed they were never warned that use of non-synthetic motor oils would cause premature engine wear.

As part of the settlement, 351,439 class members will each receive a $35 voucher toward a scheduled service, which includes an oil change. Mercedes-Benz USA also agreed to modify its warranty to cover the costs of repairing any damage caused by the problem.

Plaintiffs claimed that Mercedes-Benz vehicles were equipped with a defective “Flexible Service System”. The system is designed to monitor the vehicle’s driving condition and alert drivers when the car requires an oil change. The alleged problem with the FSS occurs when the driver uses conventional oil instead of synthetic oil.

In March 2001, Mercedes-Benz sent all vehicle owners a letter that recommended switching over to pure synthetic oils for all FSS-equipped cars to prevent engine damage."

How much will 4L cost me

Any engine with variable valve timing (vvt, vtech, etc) should run synthetics. Any buildup of sludge or varnish causes problems with them sooner or later. Run dino ok, but keep it short.

I can see how short responses can be misinterpreted. Was an opinion based on experiences researching and dealing with with variable valve timing problems. Keeping it short the mindset was...most people on here are into maintenance. But not all people maintain vehicles as they should. Infrequent oil changes, lack of maintenance, etc. For some cars you can get away with it. Others you can't. A simple google will provide page after page of vvt related issues. Researching them for my own problem the common theme for more than half is poor maintenance. Having torn one apart a vvt system it is vulnerable to problems related to sludge and varnish buildup at the OCV, its oil gallies and the vvt actuator.

You are having no problems because you are a good maintainer. Others are not. Not knowing how people maintain the general suggestion would be synthetic as not to have this issue. I did say dino ok keep it short i did not say don't use it. Thats really all there was to it.

As far as analyzing my sig, the corolla is recovering from VVT-i issues including a P1349 (clogged OCV and screen) and a sticky actuator which I was able to clean and would never attempt again. It also had a problem where the small piston oil hole returns clog causing oil consumption. Removing the pistons and drilling out hardened carbon is something I never want to do again. the Camry is under severe service. Had many sludge related problems that have subsided including oil consumption and ticking which I now suspect could have been the early stages of the corolla's vvt issues. All related to poor maintenance from prior owners including admissions to stretching out dino. When I'm comfortable I will extend the corolla.

Hope this helps explain why I wrote that and the mindset.

Don't do it!

That oil is not synthetic. Go through the advertiser's profile to see previous conversations about the integrity of his product.
You will be safer buying a brand sold at petrol stations.

Thanks.

But must it be synthetic

Integrity of his product? You must be crazy. You half baked so called mechanical engineer!
For you to come on to a thread that does not concern you, and spew lies and misinformation shows how immature you are.

You are still carrying brutal injuries from the last factual whips i unleashed on your incompetent torso!

You must have some nerve.

Trying to cast aspersions on Genuine Toyota Motor Oil from the US! I have never seen a bigger idiot than this fool

mexxy1:


That's very childish of you. I have personally bought and used this oil from autotrader2 here in PH for use on '04 Honda Pilot with no issues.

It has the API certification and meets the standards recommended by the vehicle manufacturers and, from my experience, I think it is at per with Mobil1 5W 20 which I currently use as I used the Toyota Oil for a while then switched to Mobil oil to compare. From my findings, I'm switching to Honda 5W 20 next as they're of same quality. Although, I think Mobil 1 "Extended Performance" might last longer but, I'm not going for that now.

Don't try to ruin someone's business because he doesn't agree with your opinion.

Oil plays a larger role in VVT systems. They need engine oil not only for lubrication, but also to actuate the camshafts to change the profile of the lobes.

Oil quality, condition and specifications are critical to the performance of the system. The passages and orifices can be very small and prone to sludging. Also, the oil acts as hydraulic fluid to move the actuators. If the oil does not have the correct viscosity, the behavior of the actuators will change.

The very first step I take before turning nuts and bolts is to check the oil. Dirty oil and the lack of regular oil changes can leave a buildup of sludge or debris in the passages leading to the pressure control valve that operates the VVT. If the oil is dirty and too much sludge accumulates at the valve ports, the sludge can be passed on through the cam and the valve assembly. From there, the oil passages in the cam can be compromised and could result in a cam failure due to scored journals.

Lack of regular maintenance seems to be the big factor in most of these systems. Unlike vehicles from years gone by where certain maintenance issues could be neglected, these newer engines and newer systems require the utmost in care. Stressing this point to your customers and performing the required basic maintenance per the manufacturer’s schedule will safeguard their vehicle and increase your profits.

Most late-model engines are ­factory filled with multiviscosity 5w-20 or 5w-30 motor oil, but some require 5w-40, 0w-20 or 0w-30. Be sure to follow the viscosity recommendations because many of these engines have tighter bearing clearances that require a lower-viscosity oil for proper lubrication. Thinner oils also improve fuel economy.

Prove that the oil you advertised is synthetic.



I'll rather you gave facts and figures, not thoughts.
I'm not ruining a business based on my opinion. He was asked to present details of his product but threw tantrums as he is doing right now.

autotrader2:


I don't need to prove anything to anyone, especially idiots like you. Product sells itself. Keep fooling yourself while i keep selling. Over 3,000 cartons sold so far with full compliments and appreciation from the end users. Jealousy and Envy will forever remain your lot

thebigkendo:


Am sure he told you "it is as per with mobil 1".
Is the Genuine Toyota Motor Oil Mineral, semi-synthetic or full synthetic?
Honda oil is semi-synthetic, Mobil 1 is full synthetic.. So how are they the same quality?

mexxy1:


From the pictures you uploaded, do they both have API certification or not?

Honda and Toyota have branded oils (not manufactured by them) which they recommend for THEIR vehicles and you sit here in Nigeria to criticize what the manufacturer recommended? Are you saying the time and finances plunged into research and production by these automakers is a waste?

Mobil is a business entity and, you don't expect them not to coin words into the label to describe their products and attract customers. It doesn't in anyway make them the best.

I still marvel at how you people try to push your choices down others throats.

thebigkendo:


Bros you are getting it all wrong, I am not condemning any oil brand & I never said it any oil is the best, you compared the 3 different brands of oil & stated they are at per from your experience .. My question remains.. What type of oil is Toyota motor oil... Mineral, semi synthetic or synthetic? or does API certification determine my oil change interval?
As you can see from the pictures I posted, I not a fan or loyal of any brand of oil,all I need to know is if the oil is synthetic or not
1. So I can plan my oil change intervals, 3k or 5k miles
2. Value for my money.. Why should I buy mineral oil for the same price I will get a synthetic oil which will give me longer Oil change interval

So If I buy Toyota motor oil, what oil change interval do I use? Mineral or synthetic?
Toyota 0w-20 oil clearly states synthetic... What is the 5w-20?

autotrader2:


You are such a big hypocrite. After been found and outed, you want to digress. You have stated here that the oil is fake. Now you want to change the topic! We know who you guys work for, or maybe you are all the same with different accounts. Why does this Toyota oil threaten you so much? Hmmmm, this is interesting.

Why does the vehicle manufacturer Toyota, specify 5w20/0w20 on the engine oil caps of its vehicles. See picture

That's enough for anyone with even a modicum of common sense to see that they're equivalents/substitutes.

Like i said, keep spewing hate, envy and misinformation, while i keep selling tons of cartons of Genuine Toyota Motor Oil

thebigkendo:


Please quote the post where i said its fake, I have always been asking the same question.. Which you never answer but you keep talking about hate. I no dey sell oil, I no dey work for any oil company. I am actually a customer looking for cheaper alternative oil.
All the energy you used to type all the plenty things you type.. You could have just answered my question or post a link which will answer the question.
Is your Genuine Toyota Motor Oil full synthetic or synthetic blend or mineral?

autotrader2:


Go to www.toyota.com, ask them why they called their 5w20 and 0w20 equivalents. Their answer would either reveal your ingeniousness or outright stupidity
