Oil capacity..yar i have efi version so in my car if filter is of brand "Guard" then it comes around 3.5 -3.55 while if i use Leppon then it comes around 3.6 something roughly
That's why please buy 4 Litre...Whatever oil remains in pack, take it to home with u
In Karachi, Liqui Moly is available 365 days, if u have issue in finding, u can order online too.
There are different products for flushing oil like once i bought Flushing oil of FUchs, in which they drained all oil & fill 3.5 Litre of Flushing Product in engine, then ran it for 20 minutes. After that they drained it out and yes it brought so many sludge which was not visible apparently
One time i used LM product(Liqui moly), in that case it was 300 mL for Rs. 600 so we checked oil from dip stick.
In cultus, it was almost Full so we drained almost 250 mL - 300 mL, then top up old oil with this LM Flushing liquid
Remember drainage of 250 mL old oil is necessary from bottom drain cap otherwise if u will top up, then oil quntatity will go above "Full" mark and may cause damage like seal leak and other issues so be careful
run this old oil with LM oil and run engine for 20 minutes. after that drain it after cooling
