Hi Scotty. How are you?
Today I got my Toyota Etios serviced at an authorized Toyota center here in New Delhi. One of the mechanics cleaned the air filter chamber with throttle body cleaner spray and wiped it off. Although he cleaned it after removing the air filter, I suspect that the throttle body cleaner would have made the air filter chamber oily and would block the air filter. Please suggest.

Another query is that these people change the engine oil by using an electric pipe connected to a big drum to fill the oil in the engine and don't use anything to measure the amount of oil and fill the oil by estimate. Could this cause some problems in the engine or is it fine?
Thanks and Regards.

na, it would just suck air and dry it fine cleaning it that way. But you want the oil right, so check it on the dipstick now to make sure

Ok. Thanks a lot.
