In mid March this year when the mileage was 47,000, I got it serviced at a workshop and the boss highly recommended me OWS Uber Power NA Racing Engine Oil and told me that it is very good and suitable for all NA cars. He claimed that this oil would deliver better power and guaranteed fuel saving of 5%. Well, the printing on the engine oil metal can also stated a guaranteed 5% fuel saving.
As there is no rating such as 5W-30 on the can, I asked the workshop boss about it and he told me that he doesn't know. As I have never use the above OWS engine oil before, I took his recommendation, changed the engine oil with the above OWS engine oil, flushed the engine with OWS products and changed oil filter which I paid $170.00.
Prior to using this oil, I was using SpeedMaster engine oil and KF Massimo both synthetic oil and from Japan for each service and the car was very responsive and torquey. I was achieving relatively good mileage for 50L full tank and been using BRISK Premium LGS spark plugs (the one with 4 pins) for 10,000km.
While the car was on OWS Uber Power NA Racing Engine Oil, I already felt that the engine sounds hollow and I thought that it could be due to certain admixtures of the oil.
About a month ago, I noticed that I was getting at least 15% less mileage for 50L full tank and the engine sounds rather harsh as compared to before.
Last week, I brought the car to a mechanic friend who owns a motor repair and servicing workshop and told him the above problems. From mid March 2011 till last week which is 5 months, the car only clocked 4,000km using OWS Uber Power NA Racing Engine Oil and I already encountered the above problems.
My mechanic friend initially thought that it could be the sparks plugs. He took them out and found that the plugs are still in good condition. He checked all the engine parts and found nothing wrong and even jacked up my car to check on any engine oil leak but found none.
He then asked me what engine oil I used and I told him OWS Uber Power NA Racing Engine Oil. He straight away told me that the oil is not suitable for all cars as there is no rating at all. While at his workshop, I got the engine oil changed to FK Massimo.
My car is now much lighter, more responsive at pick up and over-taking, engine is quite, smooth and beginning to achieve the mileage that I used to get before using OWS Uber Power NA Racing Engine Oil.
As OWS manufacturer has printed on the engine oil can guaranteeing 5% saving in fuel consumption but I was getting worse mileage, I wrote to the manufacturer but they have yet to reply to me. I have just written to OWS Singapore distributor and requested his reply on the problems that I encountered.
For those of you who are using or have used OWS Uber Power NA Racing Engine Oil, may I have your feedback on this oil. Thanks.
