Castrol Syntec ?

[talonXracer]

I was wondering peoples thoughts on the Castrol Syntec, not the german stuff, but the US market stuff. I needed oil quickly and grabbed some of the 5w50 to try(thought it was 5w40(old fart eyes LOL))

[Jpax]

I use that stuff all the time Doug! I have not had build up issues either unlike valvoline oil i had build up issues with that stuff in my D series motor when it was in the EK. But I have been using that in the FIT now for i would say last 6 oil changes.

LOL old fart!

[ep_hatcher_510]

i been using it for a long time now, its good oil.

[talonXracer]

Thnx Joe, I had used the German stuff in the A3 and liked it. I can really vouche for using a quality oil, the stock A2 block is in great shape with alot of miles on it.

[beechstreet]

if you are running a 40w, try out Mobil 1 0w-40. just from what ive read on BITOG, it has shown great results.

[Mighty_Mouse]

GC is one of the best oils around and probably the single best, all-around oil for the money. Their regular US stuff is just average amongst synthetics. Penzzoil Ultra 5w40 is another great synthetic that's commonly available.

I used Castrol Syntec 5w-20 for the first time during my last oil change and the only thing I've noticed different is my MPG has been better. I haven't made any other changes and I get gas from the same stations as before. I would typically get mid to high 27 mpg but now I easily get 30 with the same driving habits. It also doesn't seem to be burning off as quickly as mobil 1 oil.

How can you tell the difference in the bottle of the US castrol syntec and the german castrol?

If it is 0w-30, its German Castrol (unless its a really really really old bottle with a yellow label). Look on the back label and it says made in germany while all the other weights are made in the USA

[yyi]

ahh ic, only 0w-30 GC can be bought from the states?

[superchargedk20]

I like castrol. My boy uses the GTX on his 12 sec turbo hatch. I used both the Syntec and the new Edge. Castrol good stuff. Check his car out. Beast!

I ran Castrol for 75,xxx in a d15 and never burned a drop.

The EP has had GTX (+ WIX filter) for 90,xxx and doesn't show any buildup under the VC.

Castrol historically was formulated for small, high rpm aluminum engines-> Honda. And now Castrol is owned by BP/Amoco :)

I used Castrol Syntec 5w-20 for the first time during my last oil change . . . .

I like Castrol products generally, conventional and synthetic, although I'll have to add that Syntec wouldn't be my first choice. More importantly, however, there's a lot on this board and others regarding the potential inadequacies of 5W-20 weight motor oil, particularly if you tend to run your car hard. Google "camshaft galling" and see what comes up regarding K20 motors.

I would remove that 5w20 swill ASAP. There is a very good reason why the K20A3 was the first and LAST vehicle that Honda slappped on the 5w20 recommendation.

agreed, Now that i'm using a longer change interval i've noticed a lot more burn off with 5w-20. I just ordred 5w-30 for my next oil change. Might got the 5w-40 route if it doesn't hurt the fuel economy too much, I do a piss load of driving.

I've only found it at Autozone. One of my favorite oils. I even run it in my turbo SE-R because it "acts" like a 40 weight when hot according to BITOG.

I've also had decent results with the non-GC stuff in more pedestrian applications.

[kenscivic]

Never used it but I did buy a car with 100k miles on it one time that he strictly used traditional castrol and the motor was NASTY looking once I tore it down. So now (unfairly) I swore off castrol

[Silvercard]

What do you guys think about Royal Purple?

[beechstreet]

What do you guys think about Royal Purple?
If you're gonna spend the extra cash for Royal Purple, just go with Amsoil, Redline, or German Castrol

[Mighty_Mouse]

Sold to ricers and people who don't know any better. Waste of money.

Really? Now I'm a little scared lol. I'll just keep the revs down till my next oil change which is coming up soon. Do you think the thinner oil is giving me higher mpg? I have run different brands of 5w-30 and 5w-20 oil before and didn't see much of a mpg change though.

[talonXracer]

The 20 weight oil will gain you a few mpg's, but the potential and real damage just outweigh that.

Don't listen to people who don't really know what they're talking about when it comes to oil. Sorry talon, but that means you. There are lots of good 20wt oils out there that protect better than most 30wt oils.

No need for you to be sorry, but you are,,,LOL

the 5w20 swill is just that, swill that will ruin any engine that isnt driven like grandma.

[Mighty_Mouse]

^^^ Uneducated mechanics are always funny when they try and speak as if they know what they're talking about. Good thing that oil companies employ people with degrees. LOL

[talonXracer]

LOL

I am far from being an uneducated mechanic my friend, in fact not even a mechanic, but I am a machinist and see the results of 20 weight swill on a almost daily basis.

I wouldnt believe a single utterance from a company man,,,,Have you seen a single NEW HONDA with a 5w20 recommendation since the EP3? Nope, because it created mega problems for the stealerships.

[Silvercard]

Do you guys recommend 10w30 rp for the arizona heat?

[Distance]

what do u guys think of the castrol 5-40? the guy at autozone was telling me its only for VW and other European cars and it isnt ment to be used on a civic. also whats so good about that german castrol one?

Maybe he meant that it's not meant to be used on a Civic making next to no HP? Funny how people think that thicker oils protect better. Sad.

im boosted i was planning to run amsoil 5-40 for the hell of it and try it out but since they didn't have it at my local auto store i decided to try a differnt brand.

Yes, for you 5w-40 would make sense but so would GC which is incredibly robust and stronger than many 5w-40s. If you have Redline available locally, that's another strong oil.

so what would you say? should i just use it? its sitting near my table and most likely will be used in my car within the next few hrs. i can always go back and exchange it for something else lol.

Run it. It's nearly as thick as Amsoil 5w-40 when hot and flows MUCH better when cold.

[2004ep3hatch]

well I used 5-50 castrol and my motor made alot more noise. Now I'm using 5-40 and my motor is alot quieter. Maybe I got bad oil. But I have always used castrol syntec
