actually mineral oil still ok since most of these drivers prefer to shortened their service interval.

haha then we also cant do anything except need to educate them

your car auto or manual? do u mind reveal spec and power of your car? tq.

I'm having bot on my car as well, been using fully syn. 5w20, 5w40 and 10w40 and concluded 5w20 as my preffered choice as with it, the engine runs smoother and felt significantly faster response on the throttle too.

Guys:
Sorry for digging out an old topic. I would like to ask if anyone have moved away from the Castrol Edge Professional to other fully synthetic oils like the Petronas 7000 or Torco SR-1 for their Turbo cars?

I've been using Castrol Edge Professional but I feel this oil makes the engine "heavy" after around 6k of usages.

guanteikWhat is the oil weight used?

Cool, thanks for the reply. 0-40W or 10-40W.

Ever tried LiquiMoly Synthoil High Tech 5w40？

For BOT sometimes experience higher blow by rate, causing EO dilution after a while usage. Check your used oil against fresh one and see if the viscosity behaves similarly... If true you need to mix in 50 or even 60 weight oil.

Can I ask,

apart from regular EO change, is there anything we need to maintain the turbo in good condition?

using TD05 20g

My Turbo Preve now on 10W30 Heavy Duty Engine Oil.

Best Oil so far. Previously had Syntium 800 10W30

Periodically change the turbo oil feed and return hose, can consider changing it if more than 5 years. At least get it checked once every 2 years.

Can get clogged up with carbon/debris, slowing/blocking oil flow to and out of the turbo charger, bad situation as turbo uses the engine oil mainly for bearing lubrication.

Use only good brand name oils , nothing kills turbo faster than cheap oils just to save a few bucks

apparently, I asked my friends the same question.
and none of them actually bother to maintain their turbo..

probably mine is the smallest while theirs are AR70..


I see, thanks for sharing this.

not sure if you could answer this.
is shell helix ultra or the lexus fully synthetic engine oil, good enough?

Up to you to decide since it is your car and your money that you're spending. How much does 2 hoses cost and how much does it cost to refurbish the turbo, i believe you know the calculation.

Shell helix will be fine, lexus oil not sure as when this oil was formulated, lexus don't have any mainstream turbo engine on their cars until late last year.

Shell please , if you try to buy these oem branded ones outside of the service centre you maybe buying fakes

Take Helix Ultra, ignore Lexus oil ..........
for the sake of your turbo.

Please avoid Lexus. It is repackaged Sharlu.
Think about it. Are you willing to pour Sharlu(Lexus) into your engine?

oh, thanks for sharing.

didn't know about this. shall get shell helix for the next oil change.

Mind to share the brand?
