Would like to heard from driver who have use 15W40 engine oil in their car, what their feedback.
recently purchase a voucher from Deal.com.sg and purchase car servicing from one of the workshop in sin ming.
the engine oil that they use at pump out from oil barrel into a 4litre container, i understand that this will save them cost but the problem was they are replacing 15W40 [Eneos] into my car which all the while i am using 5W40.
i check with the staff and upon question, the voucher entilted only to 15W40 engine oil, i will have to top-up to get 5W40 engine oil. after hearing the amount to top-up, i find it not worth therefore allowing them to replace with the 15W40 engine oil.
my car is about 160,000km in mileage. therefore not too particular but would like to heard from others on this.
thanks for sharing
