Mobil vs Toyota Engine Oil ??????

[Dezaremos]

I wanted to try Toyota Synthetic Blend 15w50 for the next oil change ... Currently using Mobil Super 1000 15w40 Multigrade oil ..

Reason I wanted to try the toyota brand because its rated as 15w50 while the equivalent Mobil Super 2000 Semi-Synthetic is 10w40 ....

Some say that Toyota oil is a rebranded Mobil oil ...

How much of a difference there is between a 15w50 & a 10w40 .. I'm not after the winter numbers because we are in a tropical country ... Mas importante sa akin yung last numbers which are 50 vs 40 ....

Afaik even the best Mobil 1 oils are now group 3 hydrocracked, compared to group 4/5 oils made by Royal Purple, Redline, Amsoil and Motul.

I'm not even sure if the particular oil you mentioned is hydrocracked, it might be group 3 straight up dino oil.

If it is cheap, it's ok, but if it is priced higher than 200+/liter there are a lot of better alternatives out there. Motul, considered to be one of the top oils retails for around 600/liter.

i dont know if this is true, for i do not want the trouble of checking out.

Toyota's FS Oil daw is thicker, viscosity is at the equivalent of Shell's mineral. Tapos advice nila is one year ang change oil intervals. So if you are using an equivalent of mineral, tapos papalitan mo every year, kawawa engine mo.

Sinabi lang sa akin ito ng Customer's Cradle Shell kung saan ako nagpapa change oil.

may kakilala kami bro na service manager ng toyota na nag retire, Havoline ang FS oil ng toyota. Caltex products ang gamit nila.

its true, caltex is the supplier of oil and fuel products of Toyota motors Philippines (special thanks for vios club of the Philippines for organizing the plant tour)

read the users manual, follow the specifications indicated there, engineers did not waste time just to figure out what to write there which they are legally liable if incorrect...

Metrobank Group (TMBC, Abad Santos) uses Amalie Oil.

New mobil1 fully synthetic oil in the usa is or will be using a similar base oil as shell helix ultra. Its grp3+

Yup, bro that's what I thought. Even the mighty Delvac 1 is also now from group 3 base stock. IMHO expensive for what you get. Among the group 3 "synthetic" diesel oils, Shell Rotella T6 from the US consistently gets great UOA results from BITOGers. Cheaper too. I'm still sticking to Amsoil/Motul since my daily driver is modded. Not cost effective but I really feel the difference in group 3 vs 4/5 specially when the oil is used longer.

TS: What car do you plan using it on?

15w50? Meron ka ba hahatakin at ano klase kotse mo gagamtin?

Napakalapot nyan.

Sa mga kotse na naglalabasan nyayon 5w30 at 10w30 ang maganda gamitin.

I'm using an old AE101 Corolla GLi 1.6 4afe engine .. The rated oil for this engine as per research on the internet is a 15w40-10w40 ...

[StockEngine]

Better stick with the same viscosity....

15w50 is too thick imo.

why does toyota semi syn is 15w50 while caltex semi syn is 10w40 .... they should have the same viscosity since toyota is a rebranded caltex oil right ???

Different supply/supplier.

hmmm, just check 15w-50 is their regular oil. i am using toyota FS - 5w40. ung semi synth nila 10w-40, ung regular oil 15w-40, ung jurassic oil nila na pinakamura is 15w or 20w-50 ata. pero bihirang casa nagbebenta nito.

i worked with GT CAP group before circa 2008 - 2012 and yeah they are using caltex products for oils kung sa planta kukuha si dealership. so based on my estimate 60 to 70% of the oils they have is from CALTEX. although some dealership(s) (depende pa sa may ari) just got the oil somehwere else na approved ng planta.

i googled it & went to toyota casa .. their regular oil with green label is 20w50, their synthetic blend with red labe is 15w50 and their fully synthetic with yellow label is 5w40 ....

my question is, assuming two semi-synthetic oils are rated with the same 15w but differs on the last number (15w40 vs 15w50) .. Does the 15w50 offers better maximum heat protection at operating temperature (40 vs 50) ????

Why is 15w50 thicker than 15w40 when they have the same 15w winter numbers ???

[StockEngine]

Follow manufacturer recommendation

Yes a 0w50 will protect well for a a racing car or ferraris but they do operate at a higher speed.

Your old engine probably idles more in traffic than anything. Even if you rev it to 4000rpm a 40 weight oil will be good enough to protect your engine...a 50 weight will not have better protection than the 40 weight.

I'm also using Mobil 1000 15W40, and it's way better than 20W50. Every 5,000km oil change, surely, I'm not going back to 20W50.

You'll be fine wtih 10W40 .

Having the same winter numbers only means they should more or less behave the same way during cold starts. The actual oil thickness at operating temps is the 2nd number. Thicker isn't always better, thicker oils get you less fuel economy. Also, with group 1, 2 and 3 oils the bigger the difference between cold and hot numbers, the higher the amount of viscosity improvers. These VI give out eventually and when they do, the oil will behave more like a monograde oil with the hot number viscosity at startup. That's one reason why mineral/semi syn oils should be changed more frequently.

[weisshorn]

Bakit mo gusto gumamit ng 50 viscosity rated oil ano yan makina ng barko? Ok ang mataas kung malaki ang clearance ng mga bearing. Opinion ko lang po.
