Engine oil LIQUI MOLY or Castrol

I live in FL use liqui moly molygen 5w40 I’m stage 2 and 0 issues

I'm stage 3+ on e70. I was using 0w30 top tec liqui moly until stage 3 when I switched to 5w40 top tec.

I've used liqui moly top-tec 4200 5/30 on mine for the past few years, no problems.

Buy Castrol Edge engine oil for your Mazda 2.5, but do get the Mazda transmission oil.

I\u2019ve always preferred Castrol gold.

I've run LiquiMoly 5W-30 with the correct BMW engine ratings for over a decade now. Regular changes every 5k miles or 12 months and runs smooth as butter.

In my 323i with the 2.5L N52 engine, I use Castrol Edge 5w40 with the appropriate LL specification. Oil consumption is 3000 km per liter, with 190,000 km on the clock.

Castrol is really good considering cost and quality.

So recently I’ve noticed that on startup I get a little white smoke that dies down after warming up to about 170 oil temp I noticed this after I changed the oil I used the same green liquimoly oil my gti has been stage 2 tuned for abt 5k miles now, stock is20 and it’s a mk7 tuned it at 100k miles I’m thinking pcv. my peak boost has gone down one psi and I remember it used to hold 28.5 right before I up shifted now it’s only 26.5

La 7-8000km ce am scos din motor se chema apa colorata, nu ulei. La rece se auzeau tachetii. Nemultumit.
