Bike oil Vs Car oil

[RatbikerNate]

I don't buy bike oil, here's why....

How many more oil threads are we going to have this month?

And that article was written 18 years ago - A lot of our bikes weren't even designed or made when they wrote that.

Therefore I conclude that it is about as valid as the pope's views on my riding technique. Not to mention the fact that it came from MCN. Some things don't change.

I use Castrol GP4, not because Castrol say 'we designed this for bikes,' but because a) Honda say they recommend it, and b) because it's the same price as quality car oil. It also offers me piece of mind that I'm not damaging my engine when I rag it to the redline in 1st.

"That is just a fairly low grade oil, for normal spark ignition engines. Nothing motorcycle specific about it except that you would have difficult buying such a low spec car oil these days (the cheap mineral BP Visco 2000 that I was paying £1 a litre for is a higher spec). " - Kickstart

I totally agree. IIRC most car oils are up to the much higher SL or SM spec. The extra additives in some oils are just friction reducers, hence their effect on clutches. No damage should occur from using these oils for everyday riding.

Sorry to drag this "yet another oil" thread on, but I was in Halfords yesterday moochin' around comtemplating my next oil change, as you do. Anyway, what I was wondering was; my bike had Castrol 1 GPS 4T in it when I bought it and the guy I bought it off gave me another 4 litres for the next oil change. Well I've done the oil change and will be looking to buy some more oil in the next month or so. Castrol is API SJ - JASO MA rated, whereas Halfords own bike oil is SL and ACEA rated.

How different are these oils? Is the Halfords "better" or "worse" than the Castrol. Reason I ask is the Castrol is £28/4L and Halfords is £22/5L so it just makes economic sense if there's little difference.

First off... step away from the Halfords!

Try Busters for cheaper oil:

Though, you'd have to check up if they charge delivery, obviously.

Cheers G, Buster's have the 10w40 for £23.60 + £4.95 P&P so if i do decide on Castrol I'm as well buying it from the local dealers.

Incidentally my mechanic uses Motul 5000 when he does a service and I can get 4L for £18, is that any good?

Nothing wrong with the Halfrauds oil LeeR, the SL spec is later and minutely better than SJ. I understand that some people really do worry about their motors but there is simply no need for all the worry unless you ride a very powerful sports bike to it's limits. In fact, you are better off using a cheaper oil with more frequent servicing. I use this stuff, 10w40 semi-synthetic only £13 a bottle. Oil change every 3k.

[hmmmnz]

i worked in the bp and castrol blending and bottling plants in new zealand,
and i can tell you for a fact, that the difference between car and bike oil is next to nothing, 1ml per 1000litres is the difference in 1 additive,
the base is all the same oil (although obvisously synthetic is different from mineral )
you are wasting your time and money buying a comparable bike to car oil.

but some people have more money than sense,

Use the Castrol GTX 10/40 stuff in all my bikes (1200 bandit and GSX1400), i.e. the 'cage' stuff ... never had a problem ... and I don't hang about.

All the best ... Barry

The Halfords stuff was almost £18 for a 5 litre bottle last time I checked . Bit steep.

So now I use Wickes own brand oil - £10.99 for 5 litres. Just bog standard 10w40 stuff. No problems with the GPZ after 45k miles. I change every 3k.

[stinkwheel]

Just for information. I used castrol GTX for years but of late I have been using Motoul motorcycle oil from Hein Gericke. Comes in a 5l container at around £20-25. They were doing a free oil and air filter with every tub of oil.

I don't know if this offer is still on but it made it a worthwhile exercise for me.
