Is this oil really good of the engine? Is this the same as sem-synthetic of mobil or shell? Enlighten me because am planning to have a change oil for my altis.

I dont think the Havoline Energy is a full synth... I'm guessing that one reason why its energy saving is its because of its lower viscousity/weight (10W-30)... its not adviseable to use such in higher mileage or older engines for it may cause leaks though.
yup, it's not advisable for use on older or higher mileage cars because it's a thin oil. it's not a fully synth, but it's synth already, unlike before when it used to be mineral.
always follow the recommended oil in your car's manual...
if you want to save fuel or make your engine more fuel efficient(just like what baiskee did despite the mileage and age of his car...good for him it didn't leak) then you may try API rated Energy Conserving oils that usually have a viscosity of 5W-30 (i think there are other oils with similar visocisities but are not energy conserving)...Havoline Energy can be safely used by well maintained engines = < 5 years old.

if your gonna base it on engine design, the old engine uses the 15w-50 oil, although it can still be used on newer engines, these newer engines are actually designed and manufactured with more precise machines thus providing a thinner gap between metal to metal contacts that's why in other countries they recommend to use thinner oil like the 5w-30 of the energy. some new products actually even produce a 5w-20 rating oil. with the advancement like the vtec, mivec and vvti they would recommend you to use these thin grade oil to adequately lubricate their engine but as they also not recommend these to be used on high mileage cars running somewhere 80T km up cause it will just leak out or get burned.
yes, tatagas talaga yan. I recently used Havoline fully synth on my old ae92, tumagas nga, pero di naman yung dripping down the floor, messy lang yung engine bay. I tried adding up additive para medyo lumapot ng konti. Dont know kung tumatagas pa, papa engine wash ako and will check kung nawala tagas.
Ok lang kaya if I switch back to mineral based oil next time? di kaya manibago engine?
I have read in an article that the rating of 5W-30 of Havoline Energy ... the value 30 is quite low for our hot climate? Is this true. Does this have an effect on the engine in the long term?
Yup, the values is kinda low for the recommended temp in our climate... i cant tell the long term effects but i prefer to play it safe and use 20W-40 oil most of the time.
Its ok to use synth on the long run but what i know is that you should still change the oil regularly, and get one with a higher/thicker viscousity level. If you going from mineral to synth, might be adviseable to flush out all the old oil and gunk as much as possible.
nasa 120k na yung odo reading ko pre. good thing about hav energy, mas gumanda takbo ng oto ko, kaya ayoko mag shift sa mineral eh. mas ramdam ko yung lakas ng hatak when i started using energy.
do u think pwede akong mag switch? 145k na reading ko. i currently use Castrol GTX w/ synth guard i think 20W/40 ata yun. kahit semi synth lang? or mas ayos fully synth?

i would agreee with what tunderbolt said...it would really depend on the engine design...modern vehicles usually recommend thinner oils...if i'm not mistaken sa Ford Escape 5W-20 sa Chevy Optra 10W-30...it's safe even for our climate otherwise oil manufaturers would indicate it on the labels....
when engines operate at high speeds and high pressures, the viscosity of the oil may not be thick enough to prevent the metal parts from making contact. this will result to increased component wear and poor engine performance. ANTI-WEAR additives are included in engine oil formulations to provide longer engine life by protecting surfaces when the load and/or heat causes breakdown of the lubricant film.
most commonly used anti-wear additives are zinc. for metals parts that are not compatible or react with zinc, non-zinc (ashless) anti-wear additives are used.
for older vehicles with 100,000 km mileage or more than 5 years in age it would be safe to use thicker/mineral-based oils
HTH ;)
