Lubricant Discussion- Engine Oil / Gear Oil

[pwuser162557941033]

I see. Well, my search for an oil lab continues.

Will find them they are lying around some where in my old book records.

Please do share your oil analysis documentation.

One question: how big is the sump on each of your AMSOIL vehicles?

[rajaatta]

Crowns have 6.5 L capacity
Rocky jeep has 8 L oil sump.

One of the tiny Vitz I have has 3.5 L capacity all works perfect no sludge formation.
No varnish buildup.
Every time I open up the valve cover nice metallic colour welcomes me.

[pwuser162557941033]

Sounds good, about what I'd expect for AMSOIL claims.

I could probably switch to AMSOIL Signature 0W-40 for an entire year on my Suzuki F6A turbocharged 660cc flat tappet engine. The oil capacity is 3 liters. AMSOIL says the Signature series contains 800-850ppm of Zinc.

Their Premium Protection 10W-40 is also an interesting product, with an equally high TBN (12.1) and about 1450ppm Zinc.

It just has to make sense from a cost perspective.

Do you use a single filter for your entire OCI or do you have a shorter interval where you change the filter and top-up the oil before the oil needs changing?

[rajaatta]

I use single oil filter for f6a use 10w40 high zinc oil but double check for engine oil consumption before using the AMS oil high zinc oil.
Never ever use ams oil if the engine consuming oil on any basis like faulty rings faulty pcv breather system.
Because people uses ams and Valvoline on detoriated engine and then says this is false claim of long drain interval.
So double check then use

single filter is better option, I do same, using amsoil EA oil filter

[jatt.zaildar]

From where do you source the Amsoil filter?

[saqibhassan95]

From where do you source the Amsoil filter?

all amsoil oil dealers have filters too, Parts central, the Lube shop (lahore), WS imports etc

[pwuser162557941033]

Sure. I'm waiting on the end of my current OCI with Havoline 5W-40 to see if the engine consumes any oil.

But yeah, I think AMSOIL makes more sense for other cars in the family that are more prone to neglecting oil changes. About Rs. 19,000 for a single AMSOIL filter and 4L of 10W-40 is the same cost as two oil changes with a fully synthetic 5W-40 and a new filter each time.

Even so, what I don't like about these extended oil changes is that with owners who just want to drive their car, they never open the hood of their vehicle. It's during an oil change that they ever get a glimpse of what's underneath. On the family cars, I'd rather have more oil changes per year than less, just so I have more opportunity to look around the engine more often, check for leaks, wear items, etc.

Why thin oil has less pressure than thick oil in engine?

[hassan9251]

Vehicle: Corolla 2015 GLI 1.3 Automatic Transmission

Scenario: Mistakenly poured ZIC X7000 10W40 oil which is for diesel engines and used for around 4000 KM.

Issue: After 2000KM I started to hear loud tick noise from engine which only comes in the morning and goes away after a few(5-10) ticks. It has something to do with the rpm because even if I warm up the engine first, it still produces tick noises.

Action Taken: I realised that i have poured the wrong oil only when I went for the next oil change and poured ZIC X7 10W40 which is for petrol engines.

Current Situation: The noise is still there. The noise comes when the engine is cold and after 5-10 loud ticks it goes away. When the engine is warm on start, i dont hear the ticks. But even if I warm up the cold engine before driving, i still hear the the ticks.

I would appreciate if anyone can advise/help in diagnosing the problem or suggest an expert mechanic.

[Ali.A.Khan]

@Xulfiqar, Sir your guidance please.

For a sparingly used Turbo civic, the owner’s book states to get the oil changed every 6 months or 5K Kms but if the car is hardly driven (within the city) in the same period so should one follow the in built oil change indicator of the car? E.g. the monitor at the moment says “distance to oil change is 5,300 Kms” whereas last change was done 6 months ago and the vehicle has only been driven 1500 Kms since then. Can that indicator/sensor be completely trusted as compared to the owners book?

Hello guys. Whats the difference between Mobil 1 5W-40 and Mobil Delvac 5w-40? Also which engine oil and brand is the best for 1GD engines?

[hamzaay99]

Hi everyone! I have a honda civic vti oriel 300K km driven. Please suggest me a good engine oil. A mechanic has recommended me to use 20W-50.

[manasusman]

I have Suzuki Swift 2011 and I use ZIC HIFLO 20W50 Engine oil for it. I wanna ask about the recommendation for Engine oil change. Whether I can drive more than 5000km or not. And the reason for this.
Please guide me.

[pwuser162557941033]

Mobil Delvac 1 5W-40 is a diesel engine oil, meaning it meets API CI-4 requirements for diesel engines. Mobil 1 5W-40 is a gasoline engine oil.

Check your owner's manual and use a suitable oil. Delvac 1 5W-40, Delvac MX 15W-40, Delo Gold Ultra 15W-40 are all fine choices.

honda civic vti oriel 300K km driven. Please suggest me a good engine oil. A mechanic has recommended me to use 20W-50.

There is no reason to use 20W-50. Check your owner's manual for the manufacturer's recommended oil grade. 5W-30, 5W-40, 10W-30, 10W-40 oils from a reputable oil company are all fine depending on your budget, drain interval, and engine's condition. Again, there is no reason to use 20W-50.

I have a Civic with 200k on it, and I use a 5W-30 full synthetic.

Suzuki Swift 2011 and I use ZIC HIFLO 20W50 Engine oil for it. I wanna ask about the recommendation for Engine oil change. Whether I can drive more than 5000km or not. And the reason for this.Please guide me.

There is no reason to use 20W-50. It's a good idea to change the oil at 5000km for conventional mineral oils or semi-synthetic oils, and at 8000km for fully synthetic oils. The oil you purchase will specify whether or not it is a full synthetic. "Synthetic Technology" is not full synthetic oil.

Check your owner's manual for the manufacturer's recommended oil grade. 5W-30, 5W-40, 10W-30, 10W-40 oils from a reputable oil company are all fine depending on your budget, drain interval, and engine's condition. Again, there is no reason to use 20W-50.

Shell, Caltex, Total, ZIC are all fine oils if purchased from a reputable place like an official service station or oil depot, and they can be verified to be genuine products.

What I'm confused about is Delvac is purely diesel engine oil and I've heard its for older kinds of Diesel engine and mainly for Trucks, Buses or vehicle that need constant pulling etc. 1GD is a modern Diesel engine, one of the finest Toyota has ever produced. I believe the current gen of Revo and Fortuner have catalytic converters, don't you think that high sulpher in Delvac/Delo might harm it? Also, a lot of people are suggesting to use Mobil 1 5w-30 or 5w-40 Liqui Moli but these oils are gasoline based but now being used in light Diesel engines as well, considerably the 1GD engine, do you think it makes any difference? sorry for my ignorance.

[pwuser162557941033]

Delvac is purely diesel engine oil

Delvac 1 ESP 5W-40 is rated for both petrol and diesel engines, API CK-4 as well as API SM. You can download the product data sheet for Pakistan to confirm.

Delvac MX 15W-40 is both API CI-4 and API SL rated.

Delo Gold Ultra 15W-40 is both API CI-4 and API SL rated.

Lots of commercial users purchase large drums of Delo/Delvac etc. for mixed fleet usage, i.e. they put it in their petrol as well as diesel engines.

I've heard its for older kinds of Diesel engine and mainly for Trucks, Buses or vehicle that need constant pulling etc.

The Toyota Hiace comes with a 1GD.

Also, a lot of people are suggesting to use Mobil 1 5w-30 or 5w-40 Liqui Moli

You can always count on people to just make stuff up for no reason. If the oil does not carry the correct certification/approval/rating for your engine, do not use it.

Always use the correct engine oil for your engine. Your owner's manual will specify exactly what grade of oil to use, and what approvals/certifications it should carry. Just buy and use oil that matches that specification.

I believe the current gen of Revo and Fortuner have catalytic converters, don't you think that high sulpher in Delvac/Delo might harm it?

Where does it say that these oils have high sulfur?

[pwuser162557941033]

this oil has significantly lower levels of Zddp

What is the ZDDP content of the API SG SGO oil, and how significantly lower is it than the API SN oil?

[MADDYBOY2]

i was buying ZIC from Metro near airport
but unfortunely due to stop on import i couldnt find so i bought guard oil and its working well

[sikandaralivisionary]

yes it does it will cause your seal to leak due to overflow if you have a 1.5L or a 1.6L engine car than it takes max oil with new oil filter upto 3.5 Liters max which is 3.7 Quarts.
