GOT PROBLEMS OR ISSUES? => PETROL => Topic started by: pidim on May 12, 2014, 02:24:39

Hi everyone. I was wondering if this is normal on a GD i30 1.8L petrol engine.
Each morning I start the car from cold and everything starts normally... no issues
What I have noticed with the car (since new) is that if you start the car again around 20-30 mins after driving, it makes a "diesel rattle" sound for 1 second or so and seems to disappear when oil gets to all parts of the engine.
After 2 years, I've never questioned it because I also had a Toyota with a similar characteristic but lately it's got me thinking whether this can be fixed.
1) Is this symptom OK on a warm engine startup if oil may not have fully settled in the sump and does it happen to other owners here?
2) Is this a fault of some kind - eg oil pump?
3) Or can it be improved with a better oil - eg 0wx40
Can anyone offer any advise as to what I should tell the Hyundai dealer in tech talk.
Thanks for any help anyone can offer :)

This is only a theory, but it would be most likely the result of oil completely draining from certain areas of the motor to the sump. As the oil pump is not operating till the engine is started, there has to be a period of low oil, until supply is resumed. Other manufacturers may design their engines to leave pools of oil, which cancels the initial start up noise.
I hear it in the Diesel too, so not really anything to worry about, as long as the oil pressure light extinguishes quickly at start up.
-
Hi Phil, thanks for your quick response. Yes the light definitely extinguishes after a very short time. Do you think this would be improved with better oil?
-
Hard to say, what are you running at the moment.
Most members are using 0-30 to 5-40. The 0 oil is designed to remain thin and viscous in winter conditions. This allows the oil to drain when the engine is off, so I don't think there will be any benefit by moving outside theses ranges.
Always use good brand oils, don't skimp on quality for price, the oil is the blood of your engine.
-
Yeah I wish I knew what oil was used, but it was serviced at the Hyundai dealer, so I have no idea. I'm also about to book my next service coming up in June.
-
Many members supply their own oil filter and oils. Get a quote from you dealer, then after the price is given, ask them for a price without oil filter and oil. It should be significantly cheaper. I buy oil on special and save $ this way.

I've thought of doing that sometimes, but what's to stop the apprentice doing the job throwing in the boot of his car and giving me the standard oil?

The Getz did this at one point. Changed the oil, problem resolved. Never done it since. The replaced oil was supplied by a dealer at a scheduled service.

They do return the empties, but unless you stand and watch, I guess they could do that. I don't think they would do that though because if caught, there would be hell to pay.

It sounds to me like oil not getting to the top end as quickly as it should.
As suggested, I would replace the oil (& filter) with a quality oil of your choice that meets the specified criteria.
I use a non-Hyundai workshop so trust my mechanic that they use what I supply.
I'd try that and see how you go. :)

Just thought I would update this in case anyone is interested. I have just completed my 2 year service and used Shell Helix Ultra 5w x 40. I can say the problem has been fixed and not only that, it also rectified the "Wierd Noise on Startup" topic from cold starts.

Good news.

:whsaid: Dave swears by that oil too... Mind you he swears about AAMI, Qantas, Telstra and a lot of other stuff too... :lol:
