Castrol 5000km Motor Oil

[thor3.142]

Hello All,

Trying to find out what is the difference between castrol synthetiic blend 10w30 and castrol magnatec 10w30. Some of the Auto parts shop dealers does want to sell you magnatec when you ask for synthetic blend. Has anyone used magnatec or syn blend? Is magnatec a semi-synthetic oil? I am interested in getting a 5000 km service interval oil for a 2007 Yaris. Not a 10000km oil. A 10W30 oil.

When i ask auto dealers for a 5000km oil, they want to sell me the syntec oil

Brother, ANY oil can do 5000km.. From the cheapest conventional up to the most expensive..
That is 3000 miles, if you were changing oil any more often you would never be driving..

Personally, I don't think syn blends are worth the money seeing as they are usually only 25% synthetic included anyway (minimum amount required to call it a blend)..
For that price, there are synthetics that can be had for not much more ~$200 a gal..

So, if you really want blend, I would consider 7500km a more reasonable change interval but this of course is subject to your own driving habits and length of time between changes..

For the record, Castrol claims Maganetec to be "Part-Synthetic" whatever the hell that means

[Red Dawg]

Why do people still insist on changing their oil at 5000km.
It is wasteful and polluting.
At a time when manufacturers are extending their service intervals in order to reduce emissions, there are still people with the archaic mind set that insist on changing oil every chance they get. (waste oil is an emission).
for example, The recommended oil change interval for any BMW is 20000km or once a year whichever comes first and BMW uses Castrol Syntec 0w30, even here in T&T.
Open your owners manual and see what the recommended service interval is under normal driving conditions and help save the environment.

Red Dawg.. I agree with everything you say, but note that Castrol 0w-30 is a special spec that people in the know usually consider to be a much higher quality than your regular Castrol Syntec produced in the US.. I cant remember the fine details, but if memory serves the 0w-30 was a group 4 synthetic designed to handle the extended OCI..

Ultimately, if he wants to change at 5000km thats his business, but no sense spending money on anything more than the most basic oil then for a regular family car if you are going to be changing that often..

[Red Dawg]

The reference to BMW and the 0w30 were used just as an example.
I use Castrol GTX 20w50 in my '96 BMW and still only change it when the oil change light comes on, usually between 16000 km and 20000 km.

[CD4Accord]

I can't agree with taking a conventional oil over 8,000km, especially in the BMW, let alone 20,000km but to teach his own..

To eah his own and you will know your car but IMO, that is a bit too long with a conventional oil.

[Red Dawg]

To each his own
Notwithstanding the fact that I used to be the Service Manager at BMW and I know for a fact that the GTX is on the approved list of oils for the car in question.

Ask yourselves this question
What is the difference between a mineral based oil with an SK rating and a synthetic based oil with an SK rating?

[CD4Accord]

I said nothing against GTX, my issue is with the oil change interval selected..

But yes, this argument could go in circles forever so let us rest it there

PS. Being service manager doesn't hold much water on this forum.. Hundreds of users can list hundreds of problems they had with service or service managers from all of the dealers..

[Red Dawg]

Firstly
I was not actually advocating the use of GTX. I was just using it as an example of the longevity of modern engine oils in modern engines. Use whatever oil pleases you.

Secondly
The only reason that I mentioned that I used to be the service manager at BMW was to show that my choice for engine oil and oil change interval was not simply pulled out of thin air but in fact was an informed decision.

In an era when we should all be doing our own little bit to preserve and protect the environment, even with something as benign as not changing our oil as often, there are still people that insist on 5000 km oil change intervals. If we could all double our mileage (just an example) between oil changes we would cut waste oil disposal in half and that includes disposal of used filters. Your service costs over the lifetime of your car would also be halved.
The other side effect is that as oil sales go down and eventually so will the cost.
Most if not all new vehicle manufacturers recommend an oil change interval between 15000 and 20000 km's to make best use of modern engine oils which are designed with a longer service life.
Why would they do this? Simple answer, Used oil is an emission. It has to be disposed of.
Last point, Crude oil reserves are not going to last for ever, the oil is going to run out some day, the more we save now the better.

I apologize for trying to share a little knowledge
Apparently, somebody had a bad experience with one Service Manager and that means that all Service Managers are not to be trusted.

[CD4Accord]

Once again Red Dawg, you misunderstand me..

Firstly, I am not aiming any bullets at service managers but I am simply telling you that mentioning that you were one does not change the discussion in any way. It neither helps nor hurts your cause..

Concerning the OCI's.. I am all for extended oil change intervals but only with the correct oil.
You mentioned the 0w-30 German Castrol.. I would gladly run extended OCI's on that and any reputable synthetic.. I personally run 12,000km on my cefiro using a reputable synthetic (which I wont mention for the sake of the usuals jumping in and repping their own brand)..

I love the environment and I am more familiar with it than most, but I can't put my engine at risk for the sake of saving one extra oil change per year. Yes we need to reduce emissions and waste, but the best way to do that is to improve the re-refinement process for used oil. There are companies in Trinidad now that will collect and recycle your used oil for as little as $5 a gallon if I am not mistaken.
Concerning price decreases based on people buying oil less often, life does not always work that way.. Has vastly improved engine efficiency lowered the price of gas at all? If we were talking about a specialty product, the price would have a much stronger tie to consumer trends, but petroleum will simply be used for other processes or demands even if there was a 50% reduction in motor oil sales. Do not expect a price drop at all, especially since emerging economies such as China will simply purchase all excess raw materials that become available on the market.

A few go as high as 12k. That BMW 20k interval is definitely not the norm. You can't just make a blanket statement like that

Aye aye, don't argue with the man.. He was the service manager................................

All of which are assuming that the extended oil change intervals are being run on 0w-30 German Castrol synthetic, not lowly GTX....

[sliderz1]

question....if the vehicle manufacturer recommends the OCI at 10 000kms for example, and the OCI as recommended by the OIL MANUFACTURER is 5000kms. Who should i question or doubt for that matter?

[CD4Accord]

Well you can buy oil that can easily do 10,000km but then you have to question if the oil filter you are using can do that.. eg. OEM filters are usually better than the cheap replacements pushed by local parts places and i'm talking about a particular brand you probably will never see outside of T+T..

Anyway, alternatively, you can play it safe and do 7500km.. I don't see 7500 being THAT much of a problem on any modern conventional oil..

[sliderz1]

well the oil in question is the aforementioned 5000km rated oil. Slight sarcasm involved and directed to Red Dawg.
No hard feelings to you both...

[MG Man]

when choosing an oil for your car, the first thing you do is check the OEM specs required, ie the SAE viscosity rating, API standard rating etc. Many newer cars now Specify 'synthetic' as well, which is a fairly new convention. These specs will help you choose an oil that matches the engine's requirements as specified by the manufacturer.

As all this pertains to red dawg's point, that 20k / 1 or 2 year oil change interval is not cast in stone. Your driving style, driving conditions etc usually shortens this interval.

To that point, My R50 MINI Cooper's owners manual does make a 20k claim, and the manual specifies either BMW Long-Life oil, and lists the matching specs for the Castrol equivalent (Castrol is BMW's lubricant partner). The engine monitoring systems keep track of oil changes for you, and counts down from 20k to 0 and tells you when your next oil service is due. HOWEVER, it is NOT a straight km for km countdown. The countdown actually can run faster than actual kms driven, depending on how the car is driven. For example, I may drive 10,000kms, but the clock may countdown 13,000kms, effectively knocking 3,000kms off the interval, as a result of driving conditions.

So.........even with these magical new oils, even BMW's own branded oil, sticking rigidly to that 20k thing is insane
I still change the oil on the MINI at 10k or 6 months

Finally, many of these manufacturers requirements are for their own benefit, NOT yours.
For instance, on cars that now run a 0W20 oil, one of the key benefits is an incremental increase in efficiency (less drag), meaning you burn a fraction less gas..........the consumer will not see this benefit in their pocket, but the manufacturer in the US for example, will see a tax incentive when this fraction is applied over several hundred thousand cars. In the case of european cars, there are similar incentives. That's why euros now typically have a replaceable oil filter paper element, rather than a spin-on canister-type oil filter...the EU decided it canister-type oil filters retain a few drops of oil that can find its way into landfills etc, and the paper elements reduce this risk....I don't know if such thinking impacts on longer-drain intervals on euros, but it's worth a look

Any info on this? I know Oil Mop in particular collects by the barrel from garages but are there any companies that collect smaller amounts from the average Joe?

[MG Man]

I doubt it.......you can probably find a garage that will let you dump their oil in their drum tho

[CD4Accord]

I had the info on a place that collected relatively small amounts of used oil but I lost it of course.. Working hard to find it back

shell is the rel ting ppl, cheaper and it does work nice!

I have a 2012 Yaris and the manual recommends oil changes every 10,000 using conventional oil meeting their standards. However for dusty roads or taxis they recommend a 5,000 oil change. I'm going with the 5,000 as most roads in T&T are very dusty especially during dry periods.

Mechanics here told me that the syntecs will carry me to 10,000 using an original toyota oil filter, i'm still a little iffy about it, but i will try it next oil change.

How does anybody feel about using NP oil, once it meets the manufacturer's standards it should work right?

correct, however alot of people gonna cry down this oil for whatever reason.

Please change oil on time and youll be fine
