Oil type/changes

[Dark Authority]

Hmm..

Unfortunately, my car is at 46k kms and im one of those idiots who changes their oil every 5k's. [Used Honda FEO 10w30 Mineral Oil up to 35K. Started using Castrol 5W30 after that]

I just changed the oil as well.. -_-".. I will leave the oil to 10k for a while. Saves me money i guess.

Have to say though, car still feels alrite. Just the exhaust pipe goes black after 1 day.. soo. **shrugs

Ok the guys do recommend that it be serviced every 5000K's depending on how you drive your car; If you look at normal driving conditions to service your car every 10,000k's then you would start your car up in the morning or afternoon with a warm up and within short driving distance you will hit the hwy and sit on a steady 100k's an hour everyday.....
Otherwise most of us stop start through red lights, peak hour traffic that would not be considered as normal driving conditions, for a lot of people that would be considered has normal driving conditions because that's what your use to..... It depends how you read the small print once again.... Then of course are the one's that like to give it a bit here and there.... Written in plain english...

On page 8-13 of the handbook has a graph with recommended engine oil viscosity's.

Grade/Viscosity is temperature related - so please don't use anything less than a 10w oil - less than 10w oils are for cold areas (snow). Australia's average temperature is fairly high therefore a heavier oil is required.

I change every 5,000 kilometres oil & filter or six months - whatever comes first. Do that with all the cars - overdoing yes, but that's just me.

For normal use non turbo every 10,000 or 12 months adequate. Turbo temp makes requirement for more care.

From a teaching point for the trade - changing oil within specified time and mileage with the correct rating is well and truly adequate. Oil brand is really irrevelant providing you obey the manufacturers recommendation for viscosity and API or SAI ratings and change intervals.

From a personal point of view, I use Valvoline Durablend 15w50. I have read a good few of independent oil tests (part of the job) on a variety of oils and the Valvoline performed better than Royal Purple/Penrite/Mobil 1 and Castrol Magnatec - only marginally, but at the price - Valvoline is way in front.

I will continue to service my car every 5000k's and Allstar Tuning has won the contract to replace mazda service doing the 10,000k services where allstar were only doing the 5000k ones....

My service manager reccommended 5W30, Location: Sydney....

Read your handbook - lots recommend 5w30 oil but are doing so from advice from European or Japanese articles - obviously the articles are correct for their region.

Global Warming makes Australia a hot place - oil thins with heat.

The theory behind 5W oils is that it reduces engine wear due to being pumped quicker through the system at cold start. This is very true, but if the ambient temperature is already in the 20 degrees or even higher (no minus degree temps) there is no need for the thin oil and as the temperature rises, particularly turbo engines, the oil thins dramatically.

Thanks for the thread, guys...was going to buy the Catrol Edge 5W-30 for my upcoming 20,000 km service, but I think I may go for the Valvoline SynPower 10W-50, going for under $50 from Supercheap Auto...

Even though Penrite is a good product and I highly recommend Penrite - I would be careful using a 5w30 oil as it is designed for colder climates than Australia. Please check the temperature graph in your handbook.
Made even worse by the heat generated in turbo engines.

Just as a footnote"- I put 5w30 Valvoline durablend at the last service by mistake - engine noticeably noisier and it burnt a touch. Except for the Burrawang Cruise it has all been local "old man cruising" around town. As I service every 6 months the car has done less than 3,000 k's since, I changed to Valvoline 15w50 Durablend (oil I normally use)- engine sounds much better.
