    Had my first 10K Everest (Diesel) PMS sa casa and to my surprise they use 5W30, the same full synthetic oil they use on my Explorer. Is 5W30 really that versatile ?

    Another question i have is, i got 5 liters of Brand A 5W30 but i need 7 liters to fill up my engine. Can i mix it with brand B of 5W30 as well without any issue on the engine?

    I never mix and match oils fro different brands. You just don't know what additives they put in there and how they would react to one another.

    Best to check your manual. Rangers 2012 above model same engine with everest are factory filled with castrol made specifically for ford. Kaso naubusan na ata sila ng stock so they shifted to shell helix ultra. Both are on 5w30 and recommended drain and fill is 10k.

    Absolutely NOT! Different oils have different additive packs. Not only that, you are mixing different basestocks. Do not blend oils unless it is an emergency situation, and then change immediately at your earliest convenience.
    Don't be cheap, use the same viscosity and brand of oil.

    Don't mix and match oils. Unlike fuels that are practically identical except for a small percentage of additives, engine oils have different base oils and different additives. Also unlike fuel, you don't burn engine oil so it stays in your engine for several thousand kilometers so it's best to be consistent.

    On your other question - yes, diesel engine oils can be used for gas engines and vice versa. It's not limited to 5W-30 but to all oils. If you look closely, even gasoline engine oils have C ratings (e.g. CI, CJ) along with their S rating (SM, SN). C stands for compression and is for diesel, while S stands for spark and is for gasoline. As long as the oil meets the required API rating for your car, you can use it.

    FGP's local oil supplier is Shell but for the Ranger and Everest they use Castrol Magnatec, at least during the time that I had a Ranger. I'm not sure if FGP has also shifted to Shell for their Everest/Ranger oils.

    Yes on the first question. Most diesels now use 5w30.

    Isuzu mux/dmax uses 5w30
    Tbz&colorado uses 5w30
    Hilux/forts uses 5w30
    Rangers&eves uses 5w30
    Santafe tucson diesels also use 5w30

    On the 2nd question yes you can mix and match depending on which oils you have. Lots of guys mix and match oils at bitog. Just dont mix mineral oil with fully synthetic oils.

    Shell says 15k for the nz-fe engine when using shell helix ultra.

    Shell helix ultra 5w30 i think has an hths of 3.0-3.1
    Zic x7 5w30 has an hths of 2.8-2.9
    Shell helix ultra 5w40 has 3.8-4.0

    A lower hths gives lower fc. A higher hths means a stronger oil.

    Nice to know! But usually lower viscosity gives you a better fc right? So shell helix ultra 5w40 gives you better fc and protection compared to their own 5w30?

    Lolwat?

    Paano naging better fc ang 5w40 sa 5w30?

    I already said na hindi.

    If you're referring to tbn (total base number), it depends on viscosity.

    Vis/tbn: 5w-30/9.60 10w-30/9.74 10w-40/9.91

    You may want to search for the Zic thread for detailed discussion .

    Where did you get this info? Completely erroneous.

    For example amsoil oils have 12.6TBN across its signature range form 0w20-5w50

    Shell helix ultra 5w40 and mobil1 0w40 has more or less 12TBN.

    You may have asked where i got the info only, instead of adding "completely erroneous". Now may i ask where you got the amsoil and shell info to support your post?

    The tbn figures above are for diesels. Tbn for api-sn are of course different and much lower. When you stated tbn figures earlier, i thought you meant them as a "set" of numbers.

    Anyways amsoil and shell have product data sheets that are available

    Can someone please clarify? As I understand, TBN or Total Base Number refers to the alkalinity of the oil to counter the acidity of poor quality fuel (like high sulfur content of diesels) during the process of combustion & oxidation. As an example is sulfur being converted to sulfuric acid, which contributes to corrosion in the engine. The higher the TBN of the oil, the longer it's effectiveness in neutralizing the acidity during it's lifetime before it reaches 0. As an example, in the course of a 10,000 km life of an oil before an oil change, an oil with a TBN of 12 takes longer to get to 0 than an oil with a TBN of 10 or lower. So, an oil with a higher TBN give you a little more breathing room when doing extended oil change intervals.

    It depends on the additive package. Some fs oils have 7tbn that can last 10000mi or 15000km. Normally api-sn only requires 7-8tbn to meet api-sn requirements. For exam mag1 5w30 fmx has tbn7.9

Mineral , semi synthetic or fully synthetic?
