You can use synthetic. Choose any reputable brand.

Is Synthetic is workable on carb engine??

fycel_khan (PWUser157122009088) 2022-07-22 22:10:57 +0500 #1399

If thermostate is there but fan is dircet then it will create any issue or not. Or keep it like this.

Doesn't matter if it's carby or efi.

Taglon used to be sn/cf now its probably sn only

asimkhalidfb 2022-07-23 14:57:20 +0500 #1404

There used to be 5w and 10w30 in black tin bottles in toyota dealerships as well which were sn/cf and imported

5w30 in tin bottle is still available. 4 ltr tin in 9k.

The Petron Plus 10w30 is 4k for 4 ltr.

thermostat in system ensures that engine is always at optimum temperature. That also helps upon fuel efficiency.

If piston is on 100 standard then what engine oil to use.

fycel_khan (PWUser157122009088) 2022-07-24 12:55:04 +0500 #1409

Does thermostate has any to do with auto choke. if auto choke is not working can we put thermostate valve still.

Auto fan is mandatory for thermostate or just thermostate with direct fan works.

No idea why any mechanic is ready to do this most of them saying cultus carb engine mai thermostate ki need nhn hai its not for thst engine

capsat (ومن شر حاسد إذا حسد) 2022-07-24 15:03:39 +0500 #1410

is mechanic more educated then an engine designer or a pakwheels member who can read & understand an english service manual.

Yes auto choke works at cold start and release it with engine temperature.

Thermostat & fans working over automatic are necessary. Coolant & correct radiator cap, correct engine oil every thing is related to engine performance and fuel efficiency.

fycel_khan (PWUser157122009088) 2022-07-24 17:24:13 +0500 #1411

Sure same agree with you..

So please advice if piston is at 100 standard what engine oil will.be best.

Further if auto is not working can put thermostate

Moderator (Moderator) 2022-07-25 06:04:05 +0500 #1412

a competent electrician will take under 15 minutes to restore fan setup to work over automatic. without auto fan thermostat will take long to open rendering vehicle run HOT. Auto Fan & Thermostat are part of a thermodynamic equation to achieve perfect balance.

I still confuse what engine oil grade to use on fiest 1000 km as engine was recently rebuild with piston is on 100 standard cultus 3 cylinder it is.

Please advice grade of engine oil some say 2050 as piston is on 100 and it rebuild by hand not through machine which companies do. Some saying 10 30 or 5 30 helpme out as its pending

saqibhassan95 2022-07-25 16:19:41 +0500 #1414

10w30 will be fine
