SpitFire6 Posted July 10, 2020 Report Share Posted July 10, 2020 Hi, I found some synthetic oil sold on the internet that is very inexpensive at around £20 delivered. I couldn't find any data apart from its ACEA A3/B4, so the highest 150c group. The analysis shows it is near the top end for viscosity @ 100c for a 40 oil. Zn to me implies its 1100PPM ZDDP which is plenty for flat tappets. It also has Boron & Moly to reduce wear further. If you have high/good oil pressure this appears to be a good choice.

Clive Posted July 10, 2020 Report Share Posted July 10, 2020 40-60 psi when running and warmed up (ie not at idle!) I have used that oil. seemed to last OK, but not as good as shell helix after 12 months/6K hard use. 1 Link to comment Share on other sites More sharing options...

Hi Clive, the QX is new to me & I did initially buy it for the 206 which normally "uses" 0W40 FS @ £50. What issues did you have after 6K hard use?

Mind you, it was still less than halfords classic oil changes in 1K miles and not driven as hard! In reality, the QX oil is very good value at £20 a pop. And it seems to be eurocarparts "own brand" oil, not a bad thing at all. Cheaper usually though "carparts4less" but terrible 1970's names for companies.

SpitFire6 Posted July 11, 2020 Author Report Share Posted July 11, 2020 It is a very good oil. Someone posted the spec sheet for it. 20 pounds is unbelievable. TQX-SynPlus-FS-5W40.pdf 1 Link to comment Share on other sites More sharing options...
Badwolf Posted July 11, 2020 Report Share Posted July 11, 2020 I am sure that Eurocarparts and Carparts4less are the same company along with several others with equally bad 1970's names. How many other companies from this group can you name? 1 Link to comment Share on other sites More sharing options...

Clive Posted July 12, 2020 Report Share Posted July 12, 2020 Think I trust my eyes more than I would that little device. It just measures resistance, and says it can give false readings for oils with high levels of additives or metals such as Zinc and Moly. Just watch the oil colour change over time,and also if it starts to go watery. Link to comment Share on other sites More sharing options...
dave.vitesse Posted July 12, 2020 Report Share Posted July 12, 2020 An oil pressure gauge is the easy way to indicate when the oil is deteriorating as when this start to happen the warm pressure will start to reduce. This reduction will slowly increase with more mileage. With most good multi-grades it start to happen around 3,000 miles when the car is in every day use. Where the car is not in every day use and stands idle for most of the time then the millage will be a lot less. But remember the ambient temperature should also be taken into account when monitoring the oil pressure over a period of time. If you have already used mineral oil in the engine then changing to synthetic oil may effect the oil seals causing them to fail. Dave Link to comment Share on other sites More sharing options...
