Is it ok to have changing oil viscosities?

**sabaw** · July 25th, 2019 07:47 PM

Hi! Super newbie here so wanted to ask, I have a 2013 ford focus 2.0 and I wanted to do an oil change outside of casa. Gusto ko sana is an oil change outside once a year and casa pms once a year.

Anyway, I checked the manual and it says 5w30 ang oil spec. I noticed tho that my casa has been putting in 5w40 shell fully synthetic for the last couple of years.did a bit of research and I guess it "should" be ok, given that it might be better for our outside Temps. So anyway, checked out a service station near us, super miler, and they offer oil change using caltex havoline pro ds fully synthetic oil, 5w30.

My question is, ok lang ba change oil to havoline fs 5w30, then casa in 6 months where I'll assume they'll put shell fs 5w40, then 5w30 again after 6 months?

Also, is it better to stick to oem oil filter (about douvle the price of they procure) or is it ok to use the brand they're using (bosch, I'm assuming the non premium version).

Thank you for the help!

Just have the oil change done outside casa and use 5w30 fully synthetic oil. You can buy online to save a bit further.

If you live in the south metro area, bring your car to FordMaz in Parañaque or Las Pinas. They have the oils and filters you need. If in the north, go to Powertorq.

Hi thanks for the reply.

Is it alright though if the oil changes from w30 to w40 and then back every 6 or so months?

Edit:I just read through the havoline spec sheet at it says its not recommended for acea spec oil engines, which what the focus engine specifies on the manual. I suppose that means I have to get the shell helix 5w40 anyway.

either viscosity is ok. w30 will result to better fuel economy. every6months padin though.

use the correct diesel engine oil. do not use gasoline engine oils as they dont have the right diesel additives.

He didn’t say if it’s a diesel. The Focus 2013 models came in 2.0L and 1.6L NA gas engines with DCT.

Sorry hi yeah its the gasoline one.

Looking through the specs required by the manual, only 2 oils so far ive seen have what it needs (ACEA a5/b5)

Mobil 1 5w-30 (saw some sellers online)
Amsoil OE 5w-30 (online sellers as well)

So im deciding between these two

Ive also seen/know these oils are good

Royal Purple 5w-30 (a well known talyer in san juan sells this as part of the package)
Shell Helix HX8 5w-30 (asked in a shell service station and this was recommended, they had the helix ultra 0w-40 but i dunno if thats good as its even farther from the manual spec)
Motorcraft 5w-30 (seems to be a fan favorite on both local focus FB groups and online oil forums)

Of all of these the motorcraft 5w30 is the cheapest at 380 a liter in banawe, and ive seen good comments about it though it does not specifically state ACEA A5/B5 (though it is "ford recommended" and essentialy a ford brand)

Helix and royal purple are both good brands im sure but not ACEA A5/B5 (well not specified for RP and i think the helix is A3/B3)

So weve got M1 and Amsoil OE. Amsoil being cheap at around 400-450/L online, and M1 having an "ok" price for a "premium" brand at 600/L. My biggest contetion of course is that im buying em online, so while i do belive there shouldnt be any problems, theres just that little scratch at the back of your head, though the M1 seller does have the verification QR codes on the bottles which you can scan to see if the bottle is authentic.

Thoughts?

Is the Petron HTP (High Temp Protection) Fully Synthetic range any good? They have Rev X HTP 5w40 diesel oil (~P450/L) and Blaze Racing HTP 0w40 gasoline engine oil (~P602/L). Their oils are supposedly made from PAO (polyalphaolefin) Grp IV base oil, same as Mobil 1.

as long as it meets your engine requires. no engine spec ever required PAO.

I’m trying out Petron Rev X HTP on my Kia Carnival hoping for better protection for the turbo during long provincial drives. That plus I prefer to buy motor oil from LazMall accredited vendors in Lazada to ensure the product I buy is genuine...dami fake sa Lazada.

On a side note, how come Shell diesel oils are only rated CF, even their TOTL Ultra 5w40? They are ACEA A3/B3 A3/B4 compliant but only API CF rated.
