    Default How much oil is needed in an L15A2 (iDSI) engine?

    How much oil does an L15A2 (iDSI) engine need?
    Since my swapped engine knocks, therefore, I wish to know everything is fit. One reason of knocking can be insufficient oil.

    I used 3.7L Honda exact pack and new oil filter (which is suppose to get 0.2-0.3L oil in it too). The dip stick shows exactly in middle of dots for two limits.

    Should it be like this?

    My understanding is, it should be near the max mark and not in the middle!!

    3.7 ltr in original L12, and you end up at 3/4 from the top
    once accidentally poured full 4ltr and it was then at top dot
    its safe to pour in the remaining 0.3, wont damage/harm

    Right. Thanks.
    Honda ExactPack is of 3.7 L, so there is no extra 0.3L.
    Below 100-110 km/h there is no noticeable knocking. But at 120 and mild acceleration in the right most lane, I can clearly sense knocking.
    Read on causes of knocking and one listed cause was insufficient oil. Since that would cause heating above optimal operating temperature and early detonation.

    Finally for others to learn I knew the reason why 3.7L exact pack could only make a mark in the middle of min-max mark.
    Since the engine was new, it would have been sitting for a long time and would have drained all of the oil out of it. That oil that would stick all inside the engine when we change it.
    When we got to change the oil again, pouring in 3.7L exact pack with a new filter got it to exactly max mark. I check the next day.

    Lesson: Whenever you put oil in a swapped engine, put a little extra. Else, most probably it will knock at very high speed as mine did.

    I have started loving L15A2. The city 2005 now feels rightly powered. Its response is so positive. It gets to 140 like the original would get to 100.

    Right now, I have hi-octane in the tank but I hadn't find time to get on the motorway to checking knocking thing. Could not feel anything of the sort within the city, despite driving at 140+. But obviously cannot maintain speed above 130 and have a high divider on my side to check that slight knocking.

    Whenever I do, I will report here.

    I have the tank filled up. Will report mileage once I refill again.

    However, just to compare, on a recent trip to Kalam, we had two cars, this one (city 2005 with L15A2 engine) and a 2014 city. Both of us filled it up on way to Kalam within swat area. I did not fill it up to the brink but the other car was shaken and filled. Both of us drove within few km of each other. When the other city was exiting motorway on way back its reserve light came up, whereas I drove it all way to home near Bahria town, went to work the next day and when leaving office in the evening its reserve light came up!

    So we can say the car drove like 80 km more before reserve light came up!

    You swapped L15 idsi, you fitted it with its own wiring and ecu or same L12 ecu?

    Man that would be interesting ...

    Do share the following information :-

    1) Head Assembly or Complete L15 ?
    2) Mated it with car stock ECU and Gear or got new for L15?
    3) Cost of the Project ?
    4) Why you not opted new city i.vtec L13 or L15 due to being new and aggressive ?
    5) Pictures

    Besides I am the member of Malaysia City KE2 community and so far I heard countless issues from every Malaysian member that every City launched there (MN3 or GD8), (i.vtec,vtec or i.dsi) is comes with the knocking and fly wheels issues!

    Although they do only have CVT auto or Peddle Shifter in city !

    Yes. L15A2 (2 is for iDSI) was bought without gear for 26K from Mitho khan Ahata.
    Although it came with its own wiring (no ECU though), I have used the original wiring and everything (ECU).
    My City'05 is manual.

    This L15 was a bolt on in the city. It was even perfect match for electric wiring too.
    Till now I hadn't felt anything bad except the knocking at high speed which I believe should have resolved with proper oil level now. Though would test and report.

    You cannot tell the difference by looking. The top black cover was later put. Except the black bottle like thing near the engine oil filler.

    Thats not a good idea, you should have used its own wiring with its own ecu, your knocking is because of this reason. L15A2 and L12 have bit difference, your engine cannot perform optimum without its own ecu and wiring

    For now, I will check the knocking and if satisfied will leave it as is. Else will contact the guy for ECU.

    Guys, finally I got time to get on motorway yesterday with properly filled Honda synthetic Oil 5W30 (Rs.2400) exact pack (3.7L) and hi-octane from F-6 in the tank to check that knocking when slightly accelerating in 120-130 cruise.
    Went from Islamabad to Chakri and tried cruising several time around that speed in the high-speed lane.

    Did NOT feel an iota of knocking, alhamdulillah! It is difficult to say what resolved it, hi-octane or properly filled (up to max mark) engine oil. If you as me, I would go with the engine oil because lack of engine oil has been listed as one of the reasons for knocking even on wikipedia.

    So for now I conclude that there is no issue with wiring and ECU. The original (L12A2) is doing pretty well on L15A2. For others to again know I got the swap for 26k with old engine KEEPING the original wiring and ECU. The results are fantastic to date. Obviously the older engine wasn't good enough so I see better mileage too. Even better than a 2 years old Honda City on a trip to Northern areas recently.

    I just don't want to say it. But you might feel knocking again when u will use regular petrol. Don't know the reason why, but it has happened with me. My car's previous owner swapped L12 to L13 with the original ECU and wiring and knocking has never ended since then. Only time knocking is over when I pour it with hi-octane.
