problem after changing to fully syn engine oil and ATF

[stevenV6]

yours is s4 or V6 engine???

 

[baby_jap_wawa]

v6 engine..

 

[baby_jap_wawa]

normal v6 engine.. any help.. ? thx alots ya.. :)

 

[baby_jap_wawa]

any help.. ? thx.. :)

 

[skf]

i think 5w40 no suitable your car

 

[mengz]

i remmeber i once read that the perdana v6 is not suitable for fully-syn oil. correct me if i'm wrong.

u'r wrong. thanks.

Means ur car beg u for new V6tt engine...

actually i not sure whether is tappet sound.. how does tappet sound actually sound like.. ? mine like when press oil will have like abit *glok glok glok* sound.. if adjust tappet usually how much.. ?

i reco u come to my shop in Uptown for further checking. words can't tell. thanks.

sorry i may be wrong, but i think the perdana v6 is equipped with hydraulic lash adjusters, meaning to say, it can't be adjusted.
what oil were u on previously ? mineral/semi/full syn ?
if it is ur lash adjusters, then what u could do is to change back to the oil previously and see it there's still the tak tak tak tik tik tik sound. if there still is, and if its confirmed by ur friendly mechanic that it is the lash adjusters, then jst try and experiment with diff brands and grades of oil to find the most suitable for ur ride.

good luck bro

I dont think it is tappet sound. Erm, i owned Proton Putra for myself, and tappet is the famous prob for putra owner...
As u said, WHEN you press ur pedal there a sound *glok...glok*.
But tappet is noising no matter you hit pedal or in idle. Summore tappet might sound different.

As a few sifus quote, to reduce tappet sound I use Castrol Magnatec 10w40.
And it works... :)

10W-40, i think the best for perdana V6 engine since i use it for quite sometimes....(just my opinion)and it eliminates the tappet sound for a period of time..when it's reach nearly 4000kms....the sounds will back,nd that means u need to do an oil change after it...

Magnatec is goood last time using it hits 12k, lucky, didn't jammed engine...

hai bro ...
how old your engine ....?
old engine cant use fully syn oil la...
about the takpek sound , mitsubishi engine sure have lo , u no need go to adjust , cus after 2-3week u adjust , the sound will come back
next itme u better chance your oil to 10w40 or even 20w50 ....
if u continus use the fully syn 1 , your engine will drink oil like hell..
u can check yr oil around 2500lm .... see got lest or not...

 

[baby_jap_wawa]

my engine is eterna v6 n/a which i have used for 1 year.. in japan max limit for car on the road is 5 years.. so i guess it wont be that old.. right.. ? hmms.. if fully syn 10w40 can.. ? cos i feel that if 5w40, the engine when pick up will run lighter compared to 10-20w40-50.. do advise sifu.. hehe.. :)

 

[huakenny]

10w40 normaly in semi syn pack....fully normaly 5w40,10w50...etc

 

[baby_jap_wawa]

what would normally be the difference between semi syn and fully syn.. ?

hope tis will help

What is the difference between synthetic oil and conventional motor oil?

Choosing the right motor oil is extremely important to ensure the correct running of the engine, but what is the difference between synthetic oil and conventional motor oil?
Motor oil is designed to serve many different purposes within a cars engine. While the primary function is to simply lubricate all the moving parts and provide protection from wear and corrosion, it also is intended to keep the engine cool and free from small pieces of debris.

Conventional motor oils are made from crude oil which has been is pumped from the ground and then processed in a refinery to create a base oil. Additives are then mixed into the base oil to change the viscosity, protection properties and heat breakdown levels of the oil.

Synthetic oil is also created in a similar manner to a conventional engine oil, using a base oil combined with a series of additives. The difference lies in the fact that synthetic motor oils are created utilizing a specially "synthesized" base oil where the size of the oil molecules are all of an ideal weight and of a consistent size. While a conventional motor oil, despite the refining processes, is made up of different molecule sizes which are mixed together, along with various waxes and impurities, a fully synthetic oil is made to provide a much purer base oil, with less waxes and with a uniform ideal particle size to help increase the oils viscosity level. Added to this ideal base oil is a combination of more technically sophisticated additives than are used with the conventional oils.

The additives which are used in the production of synthetic oils can help to create an extremely stable engine oil which will sustain the correct viscosity levels across a large range of temperatures and which will flow properly at lower temperatures when compared against conventional oils. Additional friction inhibitors which are activated at lower temperatures than those of conventional oils, are generally included in synthetic motor oils, to provide improved protection for the engine from the moment of start-up.

This means that the synthetic oil is designed with improved lubricate properties and enhanced viscosity to provide superior protection from engine wear, reduced heat breakdown volatility for decreased oil consumption, improved fuel mileage, easier engine cold starting and a reduction in engine deposits.

When deciding whether it is best to use synthetic or conventional car engine oils, it is always best to bear in mind the age of the vehicle as problems and oil leaks can occur when switching to a fully synthetic oil with an old engine. This is because there can be a build-up of waxes and sludge left by conventional oils over time, which may mask worn engine seals. The introduction of a synthetic oil may cause the detergents in the synthetic oil to break down and clean-up this protective build-up which is maintaining the seal, this will then result in oil leaking through the engine seals when the oil thins as it gets hot.

Semi-synthetic oils are an alternative to buying a pure synthetic oil. These combine a certain quantity of synthetic base oil with a conventional base oil in order to provide a high quality oil which can be used to gain some of the protection benefits of a fully synthetic for slightly older vehicles. However semi-synthetic engine oils do not typically include all the synthetic oil's advanced additives.

Whilst older vehicles are frequently better using conventional oils due to the engine seals, new cars which experience normal day-to-day use with its short journeys, traffic jams, extreme temperature changes, etc, can benefit from the extra protection of afforded by synthetics, but it is always safest to refer to the manufacturer’s recommendations before making any changes.
