Does my car need engine treatment additive? I use 5w-30 fully synthetic for my Honda City, do i need to add additive? https://www.amazon.com/Restorer-Tec...ine treatment&qid=1555905438&s=gateway&sr=8-4
? for 11.99 US$ ? unlikely ? say what ?! if this was real, it would cost around $185.00 US$ per bottle and you would probably require 2.5 bottles for "maximum effectiveness" people would be selling half bottles on ebay "patent pending" doesn't mean its a legitimate product. "patent pending" also doesn't mean its a good product look at Bernie Madoff https://en.wikipedia.org/wiki/Bernie_Madoff sub prime mortgage collapse https://en.wikipedia.org/wiki/Subprime_mortgage_crisis all those really honest looking people, stealing billions of dollars, while bold faced lying to people, over and over again. the products you see them use on TV for racing cars... keeping in mind they completely re-build those engines from the ground up at a cost of around 200,000US$ including labour they can run a product then strip the engine down and re-build it, tweak it etc etc you are spending your 11.99 to save yourself from buying a new car at 20,000 US$ ? is 11.99 a fair gamble against your 20,000 $ asset ? probably not what odds would a casino give you on a 20k jackpot how many lottery tickets for 20k(cash) do you see sold for 11.99 ? not many !
No. I spent my career in the lubricants industry (Shell) and this sort of question used to come up quite frequently. Supplementary additives are not needed and are at best a waste of money. At worst they may interact adversely with some of the components of the oil. Use the grade of lubricant recommended in the manufacturer's handbook and stick to the recommended drain intervals and everything will be fine. In fact the product in the link looks to me like a scam. It is not a genuine product from the oil company Total, of that I am reasonably sure. All this ballocks about "Russian inventors" is not how a company like Total would advertise. So it is probably a trade mark infringement for a start. A trade mark infringer is not likely to be motivated to sell a decent product. Avoid.
As far as I'm concerned, "TOP 100 BEST RUSSIAN INVENTIONS" is in the same league as "Sponsored by the Mafia".
5w-30 ... ? the little shopping car to get to the grocery store or the coffee shop a few kilometers down the road once a week ? never warms up properly ? never charges the battery properly ? ...
do I need to use 0w20 engine oil? I am living in Malaysia, our daily temperature around 33oC, Is 5w40 fully synthetic good enough?
Unlikely you will need 0W. Normally the W rating is important in cold countries as it will determine the torque required from the starter motor to crank the engine in winter, which is strongly influenced by the oil viscosity at low temperature. Manufacturers in recent decades have been able to reduce the weight of batteries and starter motors by specifying 5W or 0W oils, to the point that some modern engines would not start in a cold winter with the old 20W grades. But in a tropical or subtropical climate this will be irrelevant. But read the manual and see what viscosity is recommended.
For Honda service center, they use 0w-20 oil. But now I decided not to go to the Honda center to do service, I will buy my own oil, most synthetic oil in Malaysia market is 5w-40
"brand name" service centrers do not pay their staff more money than non brand name companies. but they charge the customer about 300% more in price. they pay their executive upper managers lots of money and then feed the other half of the 150% extra profit back to the company executive cost centres. there are one or two exceptions.
what year is the engine made and what is the basic service history(how often has it been serviced and what fluids have been changed how often) ? and how many kilometers in what type of driving ? how many kilometers per average drive and roughly what speed? what is the engine size and how many passengers do you carry mostly ?
https://www.honda.ie/Page/209/honda-genuine-oils-lubricants my opinion, if you are driving gently for 1000kms(in a car less than 8 or soo years old) no faster than say 80kmph and your car is using 1 litre of oil there is something very wrong with your engine unless your living in a very cold or very hot climate and spend more time starting the car than driving it etc... adding a chemical electro-bonding mediator to your engine oil may be beneficial in tiny amounts but that is for long term gradual wear reduction NOT an increase in power(performance). (and if you get a bad batch which you wont know, then you will damage your engine which can easily cost you thousands of dollars to fix & you wont be able to get the engine additive company to pay for it, and your insurance wont cover it) how you drive makes a difference of around 200 to 500% increase in petrol consumption based on additional things like using the air conditioner all the time. using the air-conditioner uses around 10% or up to 15% more petrol poor driving ability can use up to 100% more petrol hard driving can use up to 500% more petrol driving with a family on board using the air con and electrics and stopping and starting will use around 300% more petrol
