Khyber - Performance after Complete Engine Overhaul

[speedster_101]

I drive about 2500km with SGO premium in 6 months and car gets at operating temp. I believe i can extend time period of changing oil. What do you say?

I'll be moving on to delo gold ultra on next oil change.

Isn't Delo Gold Ultra API SL?

This weekend its raining continuously in Islamabad, so thought of checking ignition system of my Khyber.

R-Spec 10mm Sparking Plug wires resistances: (Ohm-meter set to 20K setting)
Small wire: 0.70K Length: 22 inches
Medium wire: 0.76K Length: 23 inches
Large wire: 0.84K Length: 25 inches
Distributor to Ignition coil: 0.93K Length: 27 inches

These wires were bought and installed in March 2011. Working perfectly even after 5 years. High quality wires.

Ignition Coil Resistances:
Primary resistance (from positive and negative terminals of coil): 1.2 Ohm
Secondary resistance (from positive and HT terminal): 13.29 K-ohm

As primary resistance is low, smallest value was selected on ohm meter for accurate results.
The results verify that ignition coil is working absolutely fine.

Battery Voltage at Ignition coil: (Voltmeter set to DC Voltage)
DMM negative to battery negative and DMM positive to ignition coil positive.

Switch at ON position: Battery = 12.05V Coil = 11.3V
When engine is running: Battery = 14.38V Coil = 13.47V

There is a little bit voltage drop at the coil due to resistance of wires and connectors, but its negligible.

Isn't Delo Gold Ultra API SL?

Yes it is CI-4/SL. Has more zddp then regular SG SJ oil and has better additive pack for old engines. Probably best oil for flat tappet engines.

It would be great if you can mention the source.

source for using hdeo in gas engines? tons of conversations on internet, bitog.

No, source of using API SL grade oil in old engines where API SF, SG is required.

bro i've been running HDEOs specifically Delo 400, Delo rpm, Delo gold in old hondas old suzukis and toyotas and they didn't missed a beat even after 500k kms solid compression and really clean internals. this oil is best for flat tappet application. It has alot of zinc and phosphorus and has good tbn too. and its a mixed fleet oil i even used in honda as gear oil it has excellent anti foaming additives. @xulfiqar @syncview

Honda 1.6 sohc engine used on delo 15w40 after 250k kms.

Delo 400, Delo rpm, Delo Gold, all of them were API SL?

actually it has more zddp then regualar gas engine oil means you take 15w40 SL gas engine oil and 15w40 CI-4/SL diesel rated oil, the later would have more zddp hence more protection of cams plus much better cleaning because its made for diesel engines which take more abuse then gas engines and have more soot.

ZIC M is 15w-40 api SJ, wont it have better zddp and obsolete engine protection than SL?

hdeo have more zddp, zic m is pcmo.

Api grading is done according to standard api SL cant have more zddp than api sj/SG if it does csltex won't be allowed to sell it as api SL

i never said api sl would have more zddp. i said delo is ci-4/sl and if compared to a gas engine oil with api sl it has more zddp. HDEO always have more zinc and phosphorus then pcmo. and comparing delo with regular api sg or sj, i would anyday anytime prefer it over pcmo. hdeos have better tbn better protection for flat cams and more zddp compared to pcmo of same api grading.

The above discussion is based on personal experiences.
No technical information is provided for the comparison like the actual figures and amounts of ZDDP.
If only API CI-4 was written on Delo Gold Ultra, then one can make speculations about its petrol equivalence but now Caltex itself has mentioned API CI-4/SL , so it means it is API-SL.
Moreover, I do agree that diesel engine oils can be used in petrol engines but there is a reason petrol engine oils are being manufactured and recommended by automobile manufacturers. Using diesel engine oils in small 1000cc hatchbacks increases start up wear.
I will stick to SGO Premium SAE-10W40 API SG.

Hello,

I also have a khyber with same issue.. I gave it for overhaul... same pick issue with. can u give me ur no to talk? thnks

exactly
run it on this SGO if its not giving any problem. its OEM is total which is not that bad either

startup wear because its 15W? what about people using 20W50?

I just need to get this clear once and for all...... how would you compare API SG suzuki oil with delo API SL in terms of amount of zddp etc. I'm asking because you are comparing same API grades in your post.

Delo has more zddp. because its a diesel oil and has more anti wear additives. delo can take more beating.
