Exact timing of oil change/servicing

[bazzz]

Stupid noob alert.

We bought our 09 Elantra in January. It will shortly be due for it's first oil change (due at 6,000 km or 6 months). We currently have 5,500 km but are planning a trip this weekend which will add another 1,000 km on top. If we did the oil change afterward, would it matter from a warranty perspective that we were over the 6,000 km?

A similar question regarding the standard inspection/service that's required at 6 months. I won't be around that time, so it'll either be two weeks earlier, or two weeks later. Is it likely to matter when?

I know this sounds ridiculous, but I wouldn't want to jeopardize my warranty over the sake of a technicality.

It's better at the end if you do a new oil change for the long drive. But if you don't want to do it right now, it won't do any harm, just check your oil to see how the color (very dark means it's time to change)

For the standard inspection/service you can do after, But i recommend doing the oil change little earlier because it's better/smoother for the engine to run at high speed for a longer period of time.

I agree with win-star to do the oil change before your trip for two reasons. If the manufacturer estimates that the lifespan of the oil is almost at its end then having fresh oil prior to a long road trip would make sense. Also in the past, people used to say that the first oil change was important to rid the engine of any metal shavings and other debris that could be in the engine from the manufacturing process.

IMHO regardless of what you believe is right, I think not spending the 40 or 50 bucks for the first oil change before your trip might prove to be more costly over the long haul.

Engine failure due to oil is extraordinarily rare if the oil is kept properly topped up (ie: oil starvation/depletion does not occur), and I'm sure it would be 99.99% safe to make the trip. But if you want absolute peace of mind, just in case your engine falls into the 0.01% of early failures -- then get the oil changed.

Once the car is out of warranty, you might consider doing a one-time used oil analysis, when the oil comes due to be changed, and then adjusting the oil change interval accordingly. A UOA is probably not a bad idea as well to do just before a car goes off-warranty, to ensure that there's no coolant or exhaust gas leaks in the engine that need to be rectified at the manufacturer's expense.

The oil change intervals suggested by the OEM are very very liberal. They are fully aware that there will be lapses of time and they place a time on them early so that there is no possibility of any damage should you go over by several thousand kms.
Having said that, you also need your first inspection on the car. Are there any issues? Are there little squeaks and rattles? are there any livability problems? If there are, then it is a good time to have them fixed before your trip. If you have no problems at all, then taking a trip and paying attention to the little things on the car along the way is a good way of finding anything an d reporting it as soon as you get back.
So, all that to say, no, I would not do the oil change and service before the trip. If it was me, I would go on the trip, listen for every little thing along the way. Check my mileages and when I got back take it in for service and report all the little issues and have them fixed. You will not damage the car and you will not jeopardize your warranty and you will not be ostracized by the dealer.

I think you'll find that the service schedule on your Elantra recommends a service every 6000 km or three months, not every six months. So if you had been strictly following Hyundai's schedule you'd have had it in for its first oil change sometime in April already. In other words, no need to worry about whether you get the service done this week or next week based on timing alone. I'd wait until you come back and then book it in for the 12000-km/6-month Service #2, and go with the recommended schedule from that point on.

Hmm. I'm pretty sure there was nothing that is actually required before 12,000 km / 6 months in terms of servicing according to my warranty booklet. I know some dealerships suggest a three month service, but as I understand it, that isn't required to keep the warranty valid. But I'll check later just to be sure.

Thanks to everyone for their suggestions on this!
