    @sunilbsp, you could stick to Selenia for your petrol (or Diesel?). Your car looks like its in warranty. So better not experiment.

    @ vtlreja2.. Yes its SHELL RIMULA.

    @Aseem... Is 15W40 ok for areas where the ambient drops less than 10degs during winter ?

    Well u can opt for wurth for fully synthetic
    If u need semisynthetic , opt for motul 4100, it will cost 1k for 3 litres

    IMO 15W40 is better than 5W40.
    5W40 is thinner than 15W40.
    After getting engine hot 5W40 which is thin becomes more thin, that is why it easily enters in inlet manifold.
    5W40 is useful in the area where temperature is at 5° or below.
    Viscocity of 15W40 is better than 5W40.

    In warm area 5W40 is overkilling

    Actually theoretically the answer is no. Practically, I cannot really say. If the car is going to remain stagnant for longer times in winter or summer, best to pre-pone oil changes. And also like I said earlier in many posts. Diesel Marked oils like in Shell or Motul will have higher HTHS number and therefore are more suited for most modern diesels. Recently one user after using many oils suggested that Selenia had lower tappet noise. So it is a better oil in that way atleast. If one sticks to 7.5k kms change interval and not exceed 10k under any circumstances for semi-synth oil, chances are the engine will stay healthier and cleaner and not loose compression earlier than usual. Meanwhile one user who met our TFIan @ghodlur has done about 3.5lacs we are told in 2.5 years on mjd. Maybe we can get him on forum someday to share his views. Point to note is that MJD is a mile muncher and definitely very trouble free especially for daily extended highway runs. So if he has or has not experimented with oils in this time will help us know better.

  6. Eventhough Engine oil discussion beaten to Death, Many are still on the Grey side of the clarity as to which Grade can we use on 1.3 MJD for Healthy Engine life ?
    1. 5W-40 and maintain a drain interval of 10-15K Kms ! (Synthetic)
    2. 15W-40 and maintain a drain interval of 7.5K Kms ! (Mineral)-----Viscosity Change than OEM Recommends
    3. 10W-40 and maintain a drain interval of 10K Kms ! (Semi-Synthetic)-----Viscosity Change than OEM Recommends
    4. Any one recommends 5W-30 or 5W-50 ?

    Experts any opinion ?

    A quick question to our friends who have used helix hx-7: how is the seal in a new can? A breakable plastic band on the cap or is it aluminum foil seal on the spout/mouth or both? One fellow was trying to sell a can with neither..!!!!!

    @Subramanya Prasad, fact is you can go through countless posts and get a multi dimensional view, which will help you make informed choices of your own. Perhaps you did I don't know. But many do not. If they deserve to be blamed or not, not my business to comment on. Also fact is while reading an inquisitive mind comes up with a dozen more questions and does not find answers right away, so ultimately that leads to never ending confusion and trial and errors, till one learns that its not that simple an answer and could probably go against established beliefs. Like Synthetic is best for protecting and not mineral or semi-synthetic. :dead:
    What exactly do they synthesize; do all manufacturers synthesize same or similar blends; what properties do those special expensive blends or their individual ingredients have; what is the percentage of valuable and important ingredients per brand or product; are they suitable to one's specific environment and driving conditions; what are the real world practical observations; what have fact finders across the world got to say; are labs to be relied more than what users experience. The list does not end there.

    1) Why do they need to synthesize 5W40, cold start conditions?
    2) 15W40 is also described by oil manufacturers to be changed earlier
    3) 10W40 or 15W40, both are available in semi synth grade, while 5W40 selenia WR used on MJDs is semi-synthetic. Does selenia have fully synthetic oils for diesels or Fiat MJDs? It does. You can check their website. But its not sold here or recommended either by Fiat India. Which could also mean it is not needed or is an overkill, or is probably unsuitable.

    5W30 if one uses from day one IMPO can work and even give better fuel economy. But if the HTHS numbers are not equal or better than Fiat recommended oil, we are looking at potential engine damage in mid to long run. Definitely in theory and much more likely in practice also.
    5W50? the 50 means its a thicker oil and generally used for race specific applications, where extreme temperatures and conditions are present. The oil needs to form a proper film and adhere to withstand those specific applications. The downside is reduced fuel economy by a small but definite number. But protection is better. And also probably good for ageing engines. Can help with the engine compression too.
