  • Just thoughts please on what is best oil for any mx

    1.6 ….....I've got loads of it going for free just stick a bucket under my car and it's all yours :lol:

    1.8 V6....


    best budget

  • Try these and remember you get discount …


    Currently doing Fuchs Titan xtr 5w/30w at 23.99 for 5ltrs

  • what would be the best to put in my KLZE would 5w 30 fully synthetic be ok :?: :?:

  • @3cc2deed4d=djmarcopolo:

    or even go on their site and set you car as a mx6 and see what it recommends tbh i think you find its the same oil..hang on ...tick tock tick tock there you go its the same had a look for ya..

  • @0cf9fb762f=djmarcopolo:

    what would be the best to put in my KLZE would 5w 30 fully synthetic be ok :?: :?:

    I have tried 5w/30 and 10w/30 and mine seems to run better on the 10w/30.

  • I run 10w 30 in the K8 and it seems to be very happy with it, I thought maybe with the extra HP it would need something a little more special but if not I will keep to what I know then :D :D

  • I've been using this http://www.caarbitz.co.uk/Castrol_Magnatec_5W-30_Ford_4L_22117065.htm in mine.seems to love it tbh….tho i get it from tesco at £2 cheaper lol !!!

  • I use the same as nimhsy, except I use the A3 variety not A1, I too got mine from Tesco cos its cheaper, I stocked up with 4 x 4 litre tubs of it cos a few months ago it was on offer for a mere £15, I did post up in the spotted section about it….

  • I have got some semi synthetic 5w 30 that was a bargain as my dad is in the trade, he recommended not to use fully synthetic either

  • no offense, but that sounds like some old fashioned thinking. Fully Synth is whats recommended for most modern cars and bikes.

  • what is modern? post 2000? my engine is 1992, it definatley runs worse on fully synthetic 5/w 30.

  • Id say your car is modern, mines a 98, but its still built from the same components.

    Fully Synthetic lubricates better, and maintains its viscosity better at low and high temperatures. I remember reading about cars going from semi to synth and it being a bad idea due to the wear on the piston walls/oil seals, but I cant remember the source, so Im not going to detail it any further. Ive asked Oilman at Opie if he could clarify this thread further.

  • He said fully synthetic can cause problems in the engine and burn off far quicker than semi through the pistons, will ask him again and give full explanation

  • FS doesnt evaporate as much as petroleum based oil, that sounds similar to the thing I read, it was something to do with molecule length I believe, think semi has longer but unmatched molecular lengths, so doesnt lube as good as the matched lengths in FS, think the FS has shorter molecules and so it seaps past the oil rings on a worn engine, pretty sure thats right, its what I remember anyway, but time couldve distorted what was actually written.

    The reason I went for A3 is that A3 is a long life oil, A1 is a for fuel economy, and my reasoning is/was in long life oils have more base stock in it, which gives better lubrication.

    Im also dead certain I read somewhere that the fully synthetic molecules are electrostatically charged, so cling to surfaces for a much longer time, guessing thats why castrol says magnatec clings to your engine from the moment you turn the key, even though its probably all fully synth oils do it

  • Fully synthetic oils are made of equally sized molecules which helps them avoid being burned off. In mineral based oils the molecules are all different sizes, so the smaller molecules evaporate easily and burn off, leaving the larger molecules which makes the oil thicker.

    Ester based oils are the ones that stick to the metals of the engine and they are the best oils available. Magnatec only has enough of an ester content to use for advertising purposes, it's a pretty basic oil in comparison to many synthetics.

    These articles will explain more about oils




  • Thanks for replying oilman. What Fully Synthetic oil would you recommend that is economically viable to use as a regular oil service component? Is castrol edge any better than magnatec in its ester formula or is there a better one at a similar price? Many Thanks

  • Magnatec is not a proper ester oil, it's a semi-synthetic/basic synthetic, with a little ester added, basically for marketing purposes as there isn't enough to make it useful. The Edge is a far better oil, although that isn't ester based, but it is a genuine PAO synthetic, unlike the Magnatec which is mineral based.

    If you want a good oil that is well priced, Fuchs Supersyn is a good choice at £27. If want to go better than that, the Gulf Competition is £34 at the moment and that is a top end oil. The best way to save a few quid with servicing is to leave it longer. The oils I mentioned above are fine for 10k/annual servicing, so no need to change at 3k like a lot of people do.

  • Thanks oilman, maybe good to recommend a few for each engine type we all use
    1.5 + 1.6 - 4 cylinder
    1.8 V6 K8
    2.5 V6 KL series

  • For all of them, if standard, I'd say a 5w-30 is the normal choice, but a 5w-40 would also be fine. If not standard or if it gets used on track, ask us.
