Api sn & ilsac gf-5 confusions

[GoodMan7]

buddy again u came up with senseless explanation, i m using shell ultra from last 1.5 years....first time wen shell came with fully synthetic i wanted to try it one time to see the difference but to my surprised it was as good as imported oil, previously was using Zic XQ 5w40...the result of viscosity n stickiness was still there after 7k km on oil stick....not every brand of Pak made r bad and these r the International brand not local Pak brand like PSO oil, like honda civic n toyota corolla r made here same with shell oil....i guess u r using imported car too for running 10-15 years? ur topic was about fake oil not Pake made, u ve changed the topic...wat i meant to say we r all aware which is fake n which is original be it Pakistan made or imported!!

We all are born with different mentalities, power of understandings, size of our visions, wisdom, etc.. Winning this discussion will not give me any special award. We all are open to comment here. And if you are not agree, then simply ignore it or just pass away from the thread/post.
Fyr, zic xq is not being repacked in pak. because of its rare demands and hence quality is good.

My experience says that after changing the oil, if we immediately feel that pick up of the engine has been increased spontaneously, then it usually reflects the quality of the oil is not very good.
I don't know how to explain this more precisely and put more weight in my comments, but this is that I've observed seriously many times in my previous cars. Such oils run very well for first 1K, after that the graph starts coming down. And when engine goes upto 3.5K, the car itself start telling that there is need to change the oil now.

Fully synthetic & semi-synthetic oils never works like this. They work in engine with a constant flow. As many more miles you drive, the engine start getting happier periodically. The engine's pick up is same at the time of oil change and even after driving 5K.

            My dear brother , I started using Mobil 1 0W40 when  10KM on meter mean changed in showroom. In first 200km my observation was engine acceleration not as smooth as I observed in my previous ride Honda city 1300cc. I drove car upto 1000km with Mobil 1 but engine was not giving smooth driving pleasure as it was in Honda where as Toyota was 1600cc , therefore I shifted to Helix Ultra and in just 200km I observed smoothness in drive. this is not the end or final words , let me run 1000km + or 3000km then definitely I will come back here with my observation .Please wait. So for your understanding Mobil 1 was not as smooth from day one and Helix Ultra is smooth from day one and even after  200km run.  So basically shared first impression of brand / variant . Hope it clears.

well your message creates many logics to comply with. Ok.

Just for the sake of information, the 0/40 is perhaps low viscos super synthetic oil fully recommended for the new engines. But it does not bring immediate effects (especially the pick up). But after driving couple of k kms, we start feeling the engine is really happy with this oil and ultimately the drive.

later i am gonna post (new thread) some more interesting thing that i've observed while driving faisalabad yesterday. Hope it will put more weight with regards to engine's performance on synthetic oils.

im using mobil 1 0-40 since day one on my manual trim 1.8 civic 2013 ... changed it at 5000km and again recently at 10000km ... engine is running like a dream mashAllah ( in low as well as high RPM ) ... and will increase the change interval to 8k now with only oil filter change every 4k kms ... in my previous vehicles I have experienced zic, Castrol gtx magnetic and shell but this oil is way ahead in terms of performance ... atleast that's whats been my experience .. peace everyone

Dear Xulfiqar Bhai ,AOA

Well my experience of SHELL HELIX ULTRA 5W-30 was excellent. The Toyota Altis 1.6 drive was very smooth and fuel efficient as well.

Thank You for the sincere kind advise.

Now recently SHELL HELIX ULTRA comes up with 5W40 Grade instead of 5W30 in market. 5W30 no longer available .The packing of new SHELL HELIX ULTRA 5W40 is totally changed and seems locally packed.

May I have your kind comments on this change 5W30 to 5W40 . that's ok within shell ? or in 5W40 range MOBIL 1 0W40 is best ?

Request your kind guidance please !

Very interesting discussion and good to see that people want to know more & more about oil specs and quality for their costly vehicles and not believing on uneducated mechanics and shop owners.

Nobody has answered yours original question about difference of API SN & GF-5 specs. Here is answer in form of spider diagram courtsey LZ but for SM & GF-5.
Definitely GF-5 is more stringent specs and better than API. Same is the case for ACEA and OEM (Original equipment manufacturers like MB, Volvo, BMW etc) approved oils which are much superior in term of performance than API specs. GF-5 is better in fuel economy, oxidation stability and more protection in piston deposits than API.

thank you very much for the kind reply - kindly also advise the best available GF-5 Standard Oil , SHELL HELIX UTRA 5W40 or MOBIL 1 - 0W40 , 5W50 , CALTEX HAVOLINE SYNTHETIC 5W40 ??? , normally seems GF-5 Fall in 5W30 or 0W30 standards. these mentioned oils not support GF-5 , I did not saw on their packing. Kindly advise right product. thank you

Oils carrying the ILSAC rating must meet the oil standards set by the International Lubricant Standardization and Approval Committee (ILSAC). They are denoted by a GF rating prefix (such as GF3, GF4, GF5 etc). ILSAC also requires specific testing to prove improved engine energy efficiency. Typically, ILSAC ratings are applied to low viscosity oils such as 0W-20, 5W-20, 0W-30, 5W-30 and 10W-30.

Caution! Use of these low viscosity oils in older model engines, and engines not specifically designed for such oils, may result in oil consumption and engine durability problems.

I think most of oil marketing companies in Pakistan are not claiming ILSAC specs, as it take care of mostly fuel economy. Keeping in view of ambient temperature here such low viscosity oils like 0W-20 or 5W-20 are not recommended to use. Mostly 10W-30 or 5W-40 or 10W-40 oils are good to use in new cars in API SN or SM performance. 5W-50 is thick oil like 20W-50 and can be used in bit old engines.

So what to choose in 5W40 range oil , Shell Helix Ultra 5W40, Mobil 1 - 0W40 , Mobil 1- 5W50 , Havoline Caltex 5W40 ..... Can we use MOBIL 1 5W50 in 5000KM Driven Car ?????

[bunsira]

5W50 is high viscosity oil. You can select 5W40 either from Shell or Caltex. Both are ok.

AOA , Well 5W-30 Range disappeared from market in Shell Helix Ultra. Last month used locally packed Shell Helix Ultra 5W40 , previously used as per Xulfiqar Bhai advice Shell Helix Ultra 5W30, Shell 5W40 ultra brought back the same situation as it was with Mobil 1 0W40. Acceleration feels hard / harsh and slightly sacrifice in smooth acceleration with 5W40 . 5W30 was very smooth. Shell Pakistan advised to shift on Helix HX-7 5W30 . that oil is semi synthetic not fully synthetic . Looked at market and found only Total Quartz 9000 5W-30. Can anyone help ? really tired of these limitations and un availability or relevant products in Pakistan.

I dont have any experience with shell but im using caltex fully synthetic 5w40 and my car certainly feels sluggish..previously was using caltex 10w30 and had no problems at all..now il try total quartz 9000 5w30 as its the oem recommended grate for my 2008 civic 8th gen(reborn)..its an imported oil and not locally packed so thats the only benifit..plus its api-sn and ilsac-gf5...

Don't worry about the change, switch to 5W-40 you won't have any problems. 5W-40 helix ultra is a damn good oil, we're kinda lucky we can buy it here easily for cheap too.. its about 3700 IIRC

Shell Helix Ultra 5W40 in use now but not as smooth as previous 5W30 Ultra. Shell Pakistan now recommends Shell HX-7 ,5W30 its Semi Synthetic. My observation is 5W30 suits new engine and engine feels so smooth.

[ahmed2396]

I would recommend Shell Helix Ultra or ZIC XQ else if you can get Mobil 1 5W-30 ESP. Don't drag the OCI to 10-15k kms here in Pakistan with 3S OEM filters oil has max life of 8k kms anybody doing more than this is killing his car. And with 8K if you replace filter twice will be best on 4K. Nowadays in Pakistan every brand of oil is available Mobil 1 LM Valvoline Royal Purple Castrol Shell Chevron Redline Zic, but choose according to engine requirements and don't put oil in 0W, 5W30 is best else 5W40 even 10W40 can work good also. Oils are meant to clean the engine and provide cooling to the engine when wear and tear occurs and 60% of wear and tear occurs on a cold engine and when engine reaches to its optimum temp the heat cleanses up the oil also and oil starts to protect the engine.

[fahadz1]

I would personally recommend mobil1 5w/50. This is the best brand i had ever experienced. I have used shell helix ultra 5w/30 & 5w/40. i have experienced havoline synthetic 5w/40 & 10w/30.

In shell i would recommend 10w/40 the oil which comes in yellow bottle. Although its not synthetic but this oil is the best mineral oil in this grade. Close friends of mine have driven their vehicles to high mileage they have crossed the odo meter above 200000/km-hr on mobil1 5w/50 - their cars are running technically perfect with outstanding driving pleasure in four seasons where ever u are. no matters if ur driving according to the climate of punjab, sindh or other provinces. So many people have different arguments regarding mobil. Just get the right oil from the right place. i won't recommend liquimoly, caltex, pso, or any other brand. Close ur eyes and go for mobil1 without any hesitation and confusion.
