I am quoting based on your usage and car only. Myvi engine is low stressed car. No worries about LSPI or turbocharging. As you use in city area with I presume short trips, start up wear is more important than high heat high loads (track/top-speed use). Myvi has timing chain but never heard of any wear issues. Your mileage is still low so using 30 weight oil is preferable.

I would suggest following options:

Option 1- Mobil Super 1000 10W-30 API SP
Price exceed your budget slightly.

Mineral oil with TBN 7.5
Most Important is: 65% better engine wear protection^ in Sequence IVB
Sos: https://www.mobil.com/en-my/passenger-vehic...per-1000-10w-30

Petronas Syntium Cooltech claims 37.8% only wear protection.
If Mizu and Bold cannot state their test results. I assume they just pass only. There is a difference between getting C; versus getting A+ in exams. Who would you hire to work for you?

Nothing wrong with Mizu & Bold, but they blend to a price point and performance only. I have yet to seen any published reports showing Mizu and Bold having molybdenum in their oils, but Mobil Super range has. Moly is not that important for your myvi, but it is important for my vehicles

Make sure to get genuine So far I only see paulhew on shopee have genuine product. Or you can buy direct from Mobilub but probably more expensive

Option 2 - Shell Helix from Tesco / Giant
Running Fully Syn but extending oil change interval to 10000km. But you have to be careful on your usage whether it is facing oil dilution or condensation due to short trips usage

Option 3 - Diesel Oil in Bulk
This is I run on my low cost low stressed petrol cars. I have a fleet of diesel cars so I use diesel oils that come in pails/drums ie. Delo 400 MGX or Shell Rimula R4X 15W-40. They all share the same oil because I am lazy to keep inventory. I am not going to debate about petrol oils vs diesel oils.

For you, I would recommend Option 1, less headache Use genuine oil filter too

Appreciate your advise. Good insight.
Yeah, for a 10 years old car that just clock ~150K, can consider as mid life. 😃

Previously was using various brand of FS oil for ~10K on city drive and if I travel more for outstation (~15K - 20K) before I change the EO.

Will go for option 1 or 2, Need to check on the avaliability of EO when it's needed and the pricing.

Hi guys, my bmw e60 n52 petrol engine got sludge problem... recently i guess due to this sludge caused rpm unstabil and etc... I know about this Sludge problem since two years ago, and tried a few rounds short OCI , around 5k to 7k km already change oil.

Always been using Enoc Protec 5w40 full syn from my usual workshop. Two years down the road, still the same sludge, compared to previous photos from two years back, i think the sludge issue does not improve although i shortened the OCI...

Now im thinking to go a few routes to improve my engine condition:

Option 1: liqui Moly engine flush, but heard that its risky?

Option 2: Use High detergent Engine Oil, (like Shell Rimula R6?), and do a few extreme short OCI , 2000 km change once, for like 3 or 4 times... ?

Option 3: Switch to Shell Helix Ultra 5w40 from Lotus's (cheapest full syn from reputable brand and shop), and do short OCI like 2000km, for like 3 or 4 times... ?

Really worries me as I dont want to leave it just like that, and end up have to overhaul engine...

I dislike bmw e60. POS car. I dislike the e60 M5 even more

Shell Helix 5w40 change interval is 30k km ? I saw this in their official website

Is the new shell helix fuelsave worth it over the Helix HX7? Or is there something better.

And where can I get genuine Liquid Moly engine oil. Is there a recommended online seller or shop around PJ/Subang that stocks it.

Guys,

Ravenol oil in Malaysia - Any fake oil nonsense ? Kindly advise ? Currently on Shell 5W-40 ( Fully Synthetic )
ANy one here uses Ravenol oil here ? All ok ? Any problem ?


Thanks.

Online ... very risky bro ...

If you do find a suitable source - pls let us know ...

Am using ravenol on E90 since 7 yrs ago supplied by specialist workshop... I've encountered no problem despite mileage more than 170k km. Leaking seal here there normal for conti

Thanks for the feedback bro ...

Found out that LM has got its own liquimoly.os shoppe store (must've have missed that earlier). But looking at the high price, I think its better to use another brand of full syn for extended oil interval changes for my car. Maybe Aisin if I can't get Helix FS on sale since the giant near my place has closed down.

Wondering if it makes sense to change just the oil filter after 6months and change both filter and EO at the yearly mark, mileage is on the lowish side.

How low is your mileage?

I am doing annual oil change as my car hardly hit 10k in a year and so far so good. Inside the engine is still very clean when I observe changing valve cover gasket.

I normally drive around 7-8k km annually as I take train to work.

My neighbour which drives an F10 had this problem too. Happened because of BMW's 15k mileage service interval.. Due to this prolonged service interval, there was sludge building. End up engine seized and had to overhaul.. Spent 20k on it.

one of my cars at kampung is a low mileage usage per annual, max maybe 4k - 5k per annual. I did use Shell Helix Ultra FS for it and changed it once per annual. been like that for a few years, no issues on my car. I done it cz it use FS oil

Pretty sure yearly mileage is quite abit below 10k as well. Do you think KK Auto Moto is an ok online store to get Synthium 3000?

I use this...

Your sludge issue looks bad. I'd suggest decarb, get rid of all sludge. Then use Shell HU 5W40 with 10Kkm OCI. I have N52 on my E63. Bought it 7 years ago , have been on Lotus Shell HU with 10Kkm OCI from day 1. The car is 15 years now, engine still runs smooth.

Lexus engine oil seems good..any one using?

Tbh if u google N52 sludge, there are few forum discussion about this and the conclusion are due to design error, there will be a moisture inside due to the engine design. Forum said. And it does not reduce the potential having it with any specific brand, viscosity on EO.

Hi, any sifu can advice which fully synthetic oil for Ford Fiesta, 120000km+ now.
