NOAK is a good catch. Usually this not stated in oils' specs Locally Selenia Sport costs almost 4 times more than Valvoline and Motul. I wounder if it's worth it and really would do a better job in the 1.75 tbi engine....

Recently purchased S/H Alfa Romeo 4c. The owner's manual states 5W-40 ACEA C3 + FIAT 9.55535-GH2. They recommend Selenia Sport 5w40. Those are its specs: http://www.extranetpli.eu.petronas.com/dsp/pdf/ENG/stec/1636_stec_ENG.pdf...

This is good insight - on the other hand a friend with a turboed 1997 Miata got 23 FE for Castrol 5w40 after 5,000km (3,150 miles).

Hey, this is my first UOA: 2010 Porsche Boxster S 6 cylinder boxer engine 36,000 miles on the clock The oil is Mobil 1 5w50 Oil was replaced after 4,700 miles Engine oil capacity ~7.2L Oil filter - Mann Air filter - EVOMS reusable dry filter...

thx. whay just no to add semi syntetic as this is what's now inside the engine?

Hi, i need to add some oil to my MX5 and it's currently with semi syntetic. is Valvoline DuraBlend semi syntetic?

but then again in hot climate and hard driving 40 should be better over 30, shouldn't it? i don't get why local mazda insist on 30...... maybe it's because half-synt 5w40 is rare?

just to clarify - i'm not looking for longevity. replace oil every 5,000-7,000 miles is fine by me. i'm looking for better lubrication and engine protection. especialy during those hard drives.

Shell is not available also. Mobile 1, Motul and Castrols are priced 2 times than anything else. Liqui-Moly is very popular among performance cars owners (including FI-ed) - but it's only 5w40. ELF (both French and Turkish) and AC Delco are also available. So what about the main topic - 5w40...

never saw Pennzoil producsts available locally. doesn't 40 numbers says that the oil iwll be thicker at high temp than 30?

Hi everybody, so we're talking about Mazda MX-5 2008 2.0L engine. About 50% of driving is hard and high revs (mountains, x-cross, drifting, etc). Local climate is quite hot - similar to Arizona: 35 C /95 F at summer 10 C /50 F at winter Local Mazda says 5w30 oil should be used. Most syntetics...
