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.

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...

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?

is there a difference betweek sucking oil from dipstick tube and draining from the drain plug ? which one is better?

so i think its best to just use the vacuum machine.

those drain plug always lose its thread after many2 years.

number 1 cause of engine oil leaking.

just hope the pomen dont keep quiet if the tube somehow putus inside.

What car? Last time use this Shell Helix Ultra 5w40 (bought fron tesco/giant/aeon), push it to 13k-15k km interval, due to frequently outstation, on 1.6L Mitsubishi Waja engine

From where you bought your oil? Confirm genuine?

Thanks. So vrglobal and paulhew is selling genuine too? Saw their products, but still didnt buy yet as not sure genuine or not.

So products from HK can verify with qr code that leads to hk website? Any idea how to know if the products are from hk?

I see vanli selling thai products. Can this be validated by qr code?
