i'll appreciate opinions on my situation here. my car has 176k km on the clock. it's a 1.8T audi engine with k03 turbo (not Tsi). been using LM semi 10w30 but last service i changed to pennzoil fully 5w40.i dont drive much these days but i notice after 3-4 days the car sitting still, theres a lot of smoke from the exhaust upon startup and lasts about 20-30 secs.is it a bad sign or has it anything to do with switching the oil?

disregarding the smoke issue, i've been contemplating to switching again to 5w30 full syn.maybe mobil 1.thought lower viscosity will be better since i almost never rev past 3k rpm

I see I see. Parallel Importers meaning like Tesco / Giant as often mentioned here? Btw, I never known that Pennzoil is sold here locally. Probably didn't come across official distributer in Malaysia yet. Always bought my oil from SC or Petrol Station nearby. But figured out its literally burning a hole in my pocket.

@ayamxxx
Can you forward me the seller's Lazada link here or PM? Scared of fakies around the market. Thanks man appreciate it! But if its equivalent to the Shell Helix Ultra that is often mentioned here then I'd probably go get the Shell.

On the other note, nope, the Campros you mentioned are those post-09's 10's and so on one. Mine is the base, most basic Campro model a.k.a the baseline "out-dated" Campro. As per manual, it says to take 15w-50. God knows why. But i've used 5w-40 with no issues never tried the 5w-30 before. Scared to go too thin, as you know, Campro....

I see I see.

Meaning to say that, they both share the same tech, and essentially buying Shell Helix Ultra, is like buying the Pennzoil Ultra with Pureplus la.

Can I dare say they are the same oils and perform the same too? Since, Shell is parent company to Pennzoil ma.
