with w30 you get better fuel mileage along with a cleaner and quieter engine.

Sir please recommend oil for G13BB Baleno engine, the flat tappet wala scene and API SG/SJ, in that case the 20W-50 os the only available engine oil in API SG

[capsat]

G13BB

16 valve engine, for how long you've been using 20w-50

if odo is over 100,000 km switch to 10w-40 by HX series shell helix, change oil filter when change oil grade & brand.

[Horse_rider]

Odo is near to 200k, have bought this car recently, I've replaced with 20w-50 last week. Used Zic 20W50 API SG, the only API SG available. What API you recommend? ZDDP scenario

[capsat]

What API

Suzuki recommend 5w-30 or 10w-30 in SG, SH, SJ, SL or SM category.

[Xulfiqar]

look at @margallar thread of valve seals.

look at how clean that engine is getting day by day, he only followed suzuki recommendation of oils and tune up.
Previously this engine was quite varnished.

[margallar]

modern Api grade is also fine in my experience. general rule is that newer grades are reverse compatible

[margallar]

use 10w30 caltex

[mohsinmahar]

My question is pending.about guard brand oils

[Xulfiqar]

Contact them and ask whose product they are filling.

[mohsinmahar]

Dear i think no one would tell u through

[Xulfiqar]

They will, because if they are following api spec or acea spec, they will need to prove that certification.

And as we know they are not blenders, they are relabelling other brands.

E.g. the brand kendall sold in Pakistan has sister brands like conocophillips etc in usa.

E.g. walmart (supermarket) brand oil is warrenlube product, napa (parts shop) brand is valvoline product.

Assalam-O-Alaikum

I hope you are fine with the will of Allah.

I have a Toyota Vitz 2015 model. I am thinking to apply 3M Undercoat/Rubberized Coating for my car because as the car comes from Japan and because of Salt and it looks a little rusty. So I need suggestions on

how much the coating is safe for the car?
Will it actually prevents from rust after coating? because I have seen reviews and people mentioned that car actually get worsed after coating

Your guidance is much appreciated
Jazakallah

If I get the value between 200~400 mili DC ampers

where in the video did I mention amps?

[Xulfiqar]

Good lord man!!!!

did you read the description of the video and did you hear it? and do you know how to operate a DMM?

verbatim from video and literal translation.

1. coolant test is being conducted

2. negative to battery
3. Multimeter on DCV
4. positive is dipped

5. upper limit of voltage is 400 milivolts - and as we can see its on 130 and 140 milivolts - meaning this is still good coolant.

6. this coolant is 118000 or 120,000 kms old.

rest information is provided in video description.

what part dont you understand?

[Xulfiqar]

Also, what should be the temperature of coolant to perform this test ?

Or after how many minutes its advise to conduct this test after cold start ?

My jeep engine is already very loud even at idle RPMs which are 800.

Should I ask someone to sit on driver seat and push the gas pedal to fix 2K rpms ?

looks like you dont understand written language and neither do you understand video descrption.

Please find your "computer translator" so they can tell you what it means.

its obvious that the coolant is at normal operating temperature - and the engine is at fast idle or more to make it flow - (read description of video)

Its not my problem how you control rpm or that your piece of trash is louder than an earthquake or you are sensitive to hearing loud noises - use ear plugs if you like.

below is copy paste from video description

This test can help you determine if your coolant/antifreeze has depleted its add-pack. Do this test in conjunction with an SG test, the SG verifies the mixture is at 50% volume as recommended.

This test is applicable on most cars - and requires the coolant to be at normal operating temperature with it flowing - so raise up engine rpm to spin the pump faster, best results are with systems having access to the top of the radiator where coolant flows - if yours has a surge tank the test threshold would be lower.
