    Default Engine oil for Lancer 1990

    I bought mitsubishi Lancer 1990 model.
    I know its kinda old car, but as I've driven Mehran before, hence now I feel pretty luxury with it. lol.

    I checked the engine oil with dip stick and its pretty much thick and burnt black color. Though there is no smoke from silencer, but I guess its time to change it now.
    Experts plz suggest the best engine oil for it.

    Shukria.

    Hello there.
    From the previous posts, I found two liqui moly products.

    One is "Engine Flush"
    Other one is "Ceratec".

    For older cars (like I have), its good to use engine flush first. And after that use ceratec liquid.

    Engine flush will remove all oil related impurities. And Ceratec will coat a thin film of chemical inside the engine which is good for 100K and this will also keep pushing back the incoming impurities.

    Will it be good to use above chemicals instead of pouring disel engine oil ?

    Advise of experts would be v. helpful.

    Would suggest caution in using Engine Flush as it actually does flush out every loose particle in the engine/head. Use half a bottle only if u must (150ml max).

    Ceratec is a great product, and I recommend it if u can afford it (minimum PKR 2600 for a bottle).

    Use the Engine Flush as prescribed on its bottle, pour in the Ceratec, and add your choice of engine oil.

    Do note that most quality oils will already have detergents and other 'cleaning' elements added during production, and will clean the engine as it works/lubricates.

    Liquimoly engine flush is best among all the brands available.i personally used it twice in my two cars. And also ceratec is very good as it almost reduces engine running noise upto 50% and more smoother drive...

    Both products are highly recomended.actually LIQUI MOLY's all products are very good.

    Very Thank you sir for the advice.
    Yes you are right that quality oils already have chemicals that do the cleaning itself. But mine was is old car and using sn grade oils can be bit risky.
    My car engine requires SL grade oils while mostly the engine cleaning chemicals are coming in SN grade oils. I think so.

    By the way, I've noticed my average after consuming the full tank and it becomes 11.7 km/l within city on ZIC Hiflow.
    But I will check the average again specially after using engine flush and ceratec and I believe it will go above 12km/l for sure.

    Welcome.

    I didn't recommend SN spec oil!

    Use the flush as prescribed; you will probably only need half a bottle, and you don't even need Ceratec if you are going with the MOS2 option.

    Liqui Moly MOS2 is best for older vehicles too; a friend using in his 1990 Mitsubishi Galant, and satisfied with it.

    Read this LIQUI MOLY - Motor Oils, Additives, Car Care - Products - MoS2 Leichtlauf 10W-40

    @Xulfiqar

    Sir, I've asked nearly to 8 different mechanics about the PCV valve but none of them is familiar with its English name. They said if this PCV Valve has some "Desi Name" then its possible to locate it.

    I've already posted the pictures of my car engine, can you plz pin point its location? So that I can tell mechanic to check its operating condition.
    Thank you.

    PCV is the 'one way valve' that goes from tappet cover to the intake. Look for any pipe going from tappet cover to the round metal air filter box. There will be a one way valve in the start or middle of or end of the pipe. (Try taking a picture of a PCV from the Internet to show the mechanic.

    Oil use 10W-40 or 10W-30. It's good enough for pakistan conditions.

    Be careful when using engine flush especially in old engines. it does remove sludge but if the sludge is covering crank / cam seals and other areas then you may get oil leaks plus more engine noise after the flush. Best way with old engines is to change oils on time or a little earlier.

    Dirty engine oil means your oil has detergent properties and is cleaning your engine while running so you don't really need flush. If oil is clean then there are no detergent type chemicals in the oil and all the gunk is left inside the engine.

    Hope this helps.

    sir thank you.
    i found two pipes going from tappet cover. I already highlighted (encircled & arrowed) in the above picture.
    Does it mean that my car has 2 PCV valves?

    One of the pipes may have the one way valve.. Valve Looks similar to the pic I attached. If both pipes have it then you may have two. Normally found on EFI engines. Carb engines just have a simple pipe with no valve (like the Y shaped pipe in mehran tappet cover)

    remove and reinstall the belts, my mitsubishi min pajero has same problem after changing belts and despite tightening only st start up for few seconds there was sound but in my case it didn't increase in duration. reinstalling and tightniing to correct torque according to specs did the trick

    Dont grease or lube any belt. If mechanic say the belts are fully thight then just replace the old belt which makes noice. The belt has extended due to heat and replace with 1# shorter belt. Later you can adjust to last extend.
