Castrol Engine Shampoo Pre Oil Change Treatment (Flushing Oil) for Petrol 300 ml, CNG and Diesel Cars (3418104)

Good product

Added 50ml to bike engine and ran it idle for 10 minutes and waited for 10min before draining the engine oil....It worked well.....could find sludge and the old engineoil is dark with sludge from engine......This is better than other engine flushes....I woul recommend this but add only 50ml of you are using it for bikes of 1lte to 2ltr engine oil capacity.....

Very Nice Product 👌

Don't know exactly, it works or not. I cannot feel the difference.

It did a good job when doing an engine flush

Nice product

Nice oil

मुझे अपनी गाड़ी में डालने के बाद देखा, कोई अंतर देखने को नहीं मिला ।मारुति सियाज पैट्रोलपहले जितना क्लीन था डालने के बाद भी क्लीनिंग पहले जैसे ही था ।और मारुति कंपनी इंजन फ्लश डालने के लिए मना भी करती है ।Not effective
