hi guys,

just curious. any reason why you guys want to use 0w30 or 5w30? what's the expected benefit?

i tend to more 'better wear protection' word on why they come out with 10w...
i got this from agpturbo site;

"If you have a standard bearing turbocharger: The loads produced on your standard bearing turbocharger’s rotating assembly require oils with high levels of ZDDP to adequately create a film between like metals. Standard bearing turbine shafts spin between bushings (bearings) and must have a constant film of oil in order for the components to survive. This is where choosing the right oil can make the difference. We have found that Brad Penn Grade 1 is one of the best and most cost effective oil out there. Other oils that we’ve found that contain the proper levels of ZDDP are Valvoline VR1 and VR1 Synthetic NSL, and Amsoil SAE Synthetic Premium Protection. We have also used Rotellla T6 synthetic oil with much success over the years.

Additionally, we advise using thicker viscosity in these brands of oil as the heat generated by high shaft speeds will break down thin 0W, 5W, and 10W oils and cause the oil to coke inside the turbo where oil temperatures can exceed 200 degrees F. Your standard bearing turbo will enjoy that you make the right choice. These are merely suggestions by us, because we have seen failures due to improper oil over the years. These types of oils may not contain the many of the detergents that most off the shelf oils have, thus you will need to change your oil more regularly than you’re used to. If you feel that the oils you run are sufficient, we would recommend having an oil analysis completed by Blackstone Labs."

here are some pix update of my eb.

pix1: so far no sign of friction mark on my door handle

pix2: due to its size & paint quality, i found it really difficult to prevent minor scratches like this from happen on the eb. luckily had the door moulding installed

pix3: my 1st service. thank god they got the oil rite. total cost: rm123. sc: proton edar bachang.

In my earlier post, I have my suspicion level of ZDDP may be a reason why Proton suggested API-SL (higher ZDDP) rating commonly found in 10W30. Whereas 5W30 commonly have API-SM rating (lower ZDDP). This statement seems to confirm my suspicion.

But I fail to agree with the lower statement because 0W oil are almost exclusively Fully Synthetic and these are SUPPOSED to be more resistant to breaking down than Mineral (10W)

Anyone writing email to Proton on this matter? If they say 5W-30 & 0W-30 are NO NO, I can opt for Petronas Syntium 0W-40, whose viscosity sits between 10W-30 and 10W-40.

I thought modern turbo engines no longer require ZDDP level as much as older turbo engines do. And I don't think those thin synthetic engine oils easily break down for turbo applications.

hi guys,

just to update my SA got my the chassis no already (after 1 week upon booking)

said will get car end of this week as planned

i do agree with u. but SUPPOSED is what in the theory..but theoretically they know better.

yes they are some turbo application recommended on 0w (such as gtr) but then different manufacturer different requirement...we might knew the basic theory on turbo application but in reality its beyond unless we involved in the development & testing phase...

btw 0w-30,5w-30,0w-40,5w-40 sit in same range...

no harm to trying on your machine...kindly please share with us on the end result... interested to know too...

I would advise against 0W40. My reasoning are:

1. Assuming oil break down is an issue, then 0W40 viscosity range is even wider than 0W30 so will run even higher risk of oil breaking down than 0W30

2. I believe Proton is saying, don't use any 0W or 5W oil. Period. Your 0W40 would be one of them.

My 2 sen.

ask icare about the chasis no...if confirm reseave for you then your car is nearby to get

If you wanted a Bold fast, call up those small town Proton dealer who may have ready stock.

i got my chassis no already..placed booking last thursday..
quite fast..but stumbled on d/p cos my current car cannot get the target price..haizz

whats ur car color?

silver..
first time i heard silver got no queue

mine also silver. 2 weeks delivery

Updated list for TS. Hope this is of use.

Add new owner list

CFE/CVT combination too noisy for town driving. Much worst than normal AT. Only shine on highway high speed driving.

im more concern on the FC

how issit noisy?

unless you keep the turbo spinning during city drive then of coz noisy lo...
