Just a quick cautionary advise to all members running low viscosity oil. Today we are running oil as thin from 0w-20 to 0w-30 and a still today a few people who still think adding additional engine additives to the engine oil is a good idea. Their reasoning behind this choice is a old fashioned belief such additives will fortify the oil and make their engines run better. I have never been an advocate of engine oil additives,if you adding additives that means you are using the wrong specification of oil. I have just come off a phone with a 2012 Honda Jazz Hybrid owners who has been running his car with the correct grade oil..BUT had a major issue with engine additive. He had the car serviced at the dealership using Genuine Honda Hybrid green oil but added a a famous American company (three alphabets ) oil treatment additive to the engine oil when he got back home. The following day the whole family goes for a drive and the car stopped within 20 minutes of leaving his house with the oil light on, the owner quickly turned off the engine and called the AA man to recover his car. At the dealership they ran all the test to find oil level perfect and oil pressure low !! on and on draining the oil it was found to be in a thick jelly state. Luckily no engine damage has occurred by quick actions of the car owner, the oil has been drained and then flushed out and has been replaced with the green oil only. Please take note of this warning.
