Oil Change intervals

[Tom Rigbanks]

Just been looking at the Renault oil change intervals for servicing. How many thousand miles? :S Please, dear god, no one tell me they only change the oil on their cars at services?

Im pretty sure my 16 valve used to be every 6,000 miles maximum, first change after 3,000. I thought even this was alot.

 

[Ambo]

Oil technology has moved on ...

 

[Tom Rigbanks]

No marketing and advertising has moved on. Oil is still slippery wet stuff.

 

[Ambo]

So's water...stick that in!!

 

[16v_jon]

change it when it starts to loose its golden colour

So's water...stick that in!!

Without going to google and cuting and pasting, you tell me why:

1. Unbranded oil is any worse than branded oil
2. Oil i could buy 10 years ago is any different to oil i can buy today

If you can do that i wont have to tell you my statistics on advertising and marketing, which pretty much shows that the big 'Brands' target 'non-thinking', 'ignorant' 'uneducated' and 'irrational personality types' with thier advertising campains (thier words not mine).


And remember we are talking about an understressed 2 litre 4 stroke engine here. Not a gas turbine engine in a battle tank or a 1000 bhp dragster. Oil is pretty much oil. Mineral, semi synth or synth. Thats your choice.

5w40 synthetic every 6k miles for me. might do it a bit more regularly now I'm taking longer to cover 6k miles.

water is only 1% less efficient as a lubricant than oil by the way, but its the viscosity and corrosion inhibing properties of oil that u want and protection over a large temperature range.

 

[Fred@BTM]

oilman will answer your questions

 

[JonJon]

Jeez, my oil hasn't dropped or turned colour since it's 24k service which was about 6 months ago and 5k miles since. Probably something wrong with my car :/

 

[Ross M]

are you two still at it ?? (ambo + tom)
give it a break.

Working at Fawley refinery, I know the amount of extra work that goes into making higher grade, high quality oil. You get what you pay for. You can argue, but the simple fact is, we've come a long way in the last 10 years in making refinery processes focus on specific molecules strings, so the mixture can provide better lubrication across the temperature ranges, and particularly at start-up. But if you want to use Halford's own brand, thats fine by me.

Actually, maybe you should just buy Tesco Value Veggie Oil. Still oil, isn't it!

Do you actually know who makes Halfords oil? Obviously not.

As for your point on refining, well synthetic oils contains synthetic compounds. They are called synthetic because they are 'sythesised' by synthetic chemists under controlled conditions using chemical reactions. They arent refined.

Petroleum based natural oils (mineral oils) are however refined and then additives are mixted with them. Thats why they contain more impurities like waxes.

What's your job in this refinery? Obviously not in charge of anything important i hope.

 

[Ambo]

Tom, you must have fallen for the marketing to have a newer car then if only marketing has moved on in 10 years....

making you, 'non-thinking', 'ignorant' 'uneducated' and an 'irrational personality type (their words not mine).

 

[Tom Rigbanks]

No, i tried hard to find a 16v. But i couldnt wait any longer for a decent one. I must have looked at 15. Im the end my need for transport was greater than my need for a 16v.

 

[Ross M]

did either of you not think car mechanical technology has moved on never mind the oil.

Do you know who makes Halford's oil?

What is "sythesising"? Is it like when you join the dark side?

What are "synthetic chemists"? Are they copies of real ones?

What's your job, not in charge of anything important I hope. :rasp:

I'm only coming at you with this because of the negative attitude you've had since the start of this thread. Why is it impossible to believe that refining/manufacturing processes have improved in the last 10 years? Sure, there's some embellishing of facts and even some BS in the marketing of oils, but his is the case with any product you can by for any purpose. You're saying there's no benefit of buying a name brand either? Now I know in some cases that the main manufacturers of products supply two or more sellers of the goods and they brand them with their own labels, even though it's the same product. This isn't always the case though. I'll take one example that's specific to Halford's to keep it more relevant. I like Bosch wiper blades, I think they work well. I do not like Halford''s own brand wiper blades, I think they are s**t. But they are both simply rubber aren't they? Rubber hasn't changed in the last 1000 years or whatever has it? Well I don't know why it is, but branded wiper blades have a type of rubber more suitable for their task.

So if we assume there is more than one company refining oil and manufacturing synthetic oils, couldn't we be right in thinking it's possible these different companies are producing different qualities of oil?

 

[Ross M]

^^ rubber is made from oil too .... very relevant.

 

[Tom Rigbanks]

Do you know who makes Halford's oil?

Yes Castrol. Halfords and Castrol and owned by the same company. Check it out at the companies house website if you want more information.

What's your job, not in charge of anything important I hope. :rasp:

Yes im a chemist. I work in a lab that has been researching interactions between oil constituents and industry additives for the last two years. I have 4 papers ready for publication in peer review journals, and have lectured in front of the Royal Society of Chemistry on my subject. So you could say im an expert in my field.

Any more questions?

 

[Ambo]

Of course, but we were talking oil!

GAZGB...well said!

Please, which Halfords oil would you recommend then? I know they do a 5W-40 fully synthetic thats normally £29.99. This or something else?

 

[Gmk1]

so what would be the best oil to use in the 1.6 16v engine with 49k miles on it?.. what about this gtx magnatec stuff ias it worth the extra money?

 

[MarkM]

Im pretty sure my 16 valve used to be every 6,000 miles maximum, first change after 3,000. I thought even this was alot.

Is your reasoning that based on oil technology remaining unchanged and servicing intervals doubling that a modern car engine will wear faster then an engine useing oil from ten years ago but serviced more often?

 

[Tom Rigbanks]

Just buy the manufacturers recommended oil. But dont buy branded oil (such as castrol, elf, mobil 1 or Shell). Unbranded stuff is the same, but you dont pay for the name.

If your car uses 5w 40 fully synthetic, ALL 5w 40 fully synthetic oils are the same. If you buy if from elf it costs maybe £40 for a change. If you get it from Halfords then its £20 a change.

Why pay £20 for an elf sticker on the bottle rather than a halfords one?

 

[Tom Rigbanks]

One of my engines has been run on semi synthetic oil for 12 years. Not particularly expensive or good oil by todays fully synthetic standards. Just bog standard 10w 40. However at rebuiold time of 140,000 miles there was minimal wear on the engine (verified by Nick Hill). All down to the fact that the oil had been changed regular as clock work every 6,000 miles from new.

 

[tidyclio]

so how about asda 10w 40 own brand £3.49 for five litres are you trying to say this is just as good as say the gtw maganatec stuff?
yes you do pay for a name but you seriously can't be telling me ALL oil's of the same grade are the same?
so basically theirs just a big huge container of oil somewhere?asda,shell,castrol,elf etc all get their oil from the same source?

 

[Tom Rigbanks]

10w 40 semi synthetic is 10w 40 semi synthetic. 5w 40 synthetic is 5w 40 synthetic. Manufacturers can't put one thing on the bottle and then fill it with a different oil. If they claim a particular temperature range for the oil it will have that temp range. If they claim its synthetic, it will be synthetic.

You buy whole milk, you get whole milk. You buy semi skimmed you get semi skimmed. Doesnt matter if you buy it from Tesco, Asda or Sainsburys, it all comes from the same few dairys. Would you pay twice as much for milk in Tesco if it had a Mobil 1 sticker on the bottle?

 

[Lagerlout]

Hmmm.... Tom Rigbanks.....

Is that an anagram of something?

 

[Tom Rigbanks]

No, ethingmos is an anagram of something

 

[Lagerlout]

Lol!

Nice to meet you Tom. I'm something of a Maverick myself..

 

[Tom Rigbanks]

Nice to meet you too. Everyone seems very friendly. Almost feel like im being treated like royalty.

 

[Lagerlout]

Hehe.... that's because you have a 172, which is the car of kings.

 

[Ambo]

This just confirms what sh*te you talk...I am using the manufacturers recommended oil at £22 a change! Infact, thats £8 less than Halfords 5W-40.....per change. Excellent, I can pay -£8 for the Elf sticker on the bottle...

Banned...:approve:

 

[Day]

The King is dead (again)

Long live the King.

 

[Lucas]

Do you know who makes Halford's oil?

Halfords and Castrol and owned by the same company. Check it out at the companies house website if you want more information.

Are you sure? I'm pretty certain Halfords aren't owned by BP (who own the Castrol brand), but I'll happily be proven wrong.

 

[GazCB]

You buy whole milk, you get whole milk. You buy semi skimmed you get semi skimmed. Doesnt matter if you buy it from Tesco, Asda or Sainsburys, it all comes from the same few dairys. Would you pay twice as much for milk in Tesco if it had a Mobil 1 sticker on the bottle?

Not true. Some brand's full-fat is slightly creamier than other brands. Due to storage and transportation (or even something else) Spar milk will ALWAYS go off before ASDA milk.

What a manufacturer claims there oil is, is possibly less accurately described or has a larger tolerance than more expensive oils. If I set up some alkane cracking kit in my shed and start selling the products of my "refinery" for a cheap price, I've got you as a customer have I Tom? Seeing as all oils are the same.

So yes this example is a huge exageration, but surely you must see my point?

 

[Ross M]

why was he banned ? lol

 

[leon RT]

Because he couldn't read I guess.:rasp: I mean, I didn't actually mention the word synthetic in my post. Probably because the stuff I was talking about was mineral oils.

Arguing must be in human nature, we just love it don't we?!?

BTW gaz, I think you'd probably blow yourself sky-high before you managed a decent oil from a shed-refinery. As would I.

 

[kully]

ok so i use 5w40-silkolene how long before my nxt change .
cup 172 less than 7k per yr average mileage :approve: ???????????????

 

[Sami]

Right so someone wants to tell me Halfords 5w40 fully syn. is the same as Silkolene dream on! You get what you pay for, you may like to think that Halfords fully 'synthetic' is the same as Silkolene synthetic but you would be very wrong.

At the end of the day if you really want to keep your engine top notch you want to put top notch oil in, not halfords own brand.
