what 10w-30 brand to choose?

**jehodl** · August 3rd, 2010 05:57 PM

My corolla is up for an oil change soon and im planning to shift to the thinnest possible oil which is 10w-30. I checked the manual and 5w-30 is rated only for use in extremely cold weather (below 0). Engine is the 2E carburated one.

1.) is it to switch to 10w-30 oil, im currently on 15w-40? (not sure kung yun yung specs ng oil pero I use the yellow shell helix)

2.) can anyone suggest a good brand and estimated market price?

3.) is 10w-30 fully synthetic or semi-synthethic?

salamat marami.

Highly available po ba ang royal purple kahit sa mga Shell Station Service bays? planning to have an oil change ASAP.

thanks!

Went to ACE hardware today. Wala na kasing 10w30. Sabi nung attendant, pwede din daw yung Castrol na 10w40 so that's the one I got for 1K. Yung Shell Helix kasi na 10w40 is 1.4K.

Tama ba yung advice nung attendant saken? In any case I can return the item for replacement w/in 7 days naman.

I also owned an EE100 with a 2E carb engine before. And I believe it requires a 20w-50...correct me if I'm wrong ah.

And since your car might be somewhat 17yrs old, I dont think changing to a thin oil will do it good.

I suggest you stick with 20w-50 na oil. You can buy a liter from Toyota at Php 155 each, Toyota oil is manufactured by Chevron (Caltex). Shell Helix Super (Yellow) is also 20w-50 and costs around Php 215 per liter.

What I did before is use the Toyota oil and change oil every 3k kms reading and change sparkplugs also to Toyota Denso at Php 55 each. Since Php 155 per liter, hindi masakit sa budget and alaga pa makina.

You can try 10w-40 if you want, Shell Helix Plus (Blue) costs Php 320 per liter......if 10w-40 and 10w-30 or 5w-30 does not drip out of your engine overnight then good.....but the bottomline is, if the viscosity is fit for the age of your engine.

Sa Toyota 2E na makina ko gamit ko iyong Mobil Super 1000 15w 40 multigrade.
1 gal. 800 plus sa Ace hardware okay naman.

Hindi po ba for diesel engines and 15w40?

**meledson** · August 10th, 2010 02:28 PM

kung hindi mag leak ang 5W-40 or 5W-50 magandang gamitin ito sa makina.

ang advantage ng mas lower first number ay kung at what temp ma achive ng oil ang tamang viscosity na kailangan ng makina. iyong upper number naman ay ang para sa upper limit na tama ang viscosity.

before I was planning to use the toyota mineral oil na 20W-50. kaso paraang malapot at matagal mag warm up. so nag 10W-40 na lang ako ng semi synthetic. good for 7,000 km, pero magpapalit ako every 5,000 km.

ang SAE numbering system ay ginawa para sa pag grado ng viscosity o lapot. Yung letrang W sa unang numero ay notation sa "winterized oil" na may kinalaman sa paggamit sa malamig (below zero) ambient air temperature na lugar

50 - malapot, pang 2.5 liter engine gas o diesel, pwedeng 2.0
40- pang kotse o diesel na 1.6 liter displacement, pwedeng 1.8
30 - pang winter sa 1.4 liter engine

Kung mas malaki ang engine displacement, mas mataas ang rpm ng makina. kaya kung SAE 50 ang gamit sa 1.6 liter engine, hirap ito. Kung 30 SAE naman gamit sa 2.0 liter engine, manipis ang oil kaya maaaring mag-wear ang mga rotating components - bearing, cam, piston ring.

Para sa mga kotse sa pilipinas, walang gaanong pinag iba ang 15W-30 sa 5W-30, dahil parehong SAE 30. Ang winterized number -15W, o 5W ay mahalaga lang kung gaano kalamig ang air temperature kung iistart ang engine - halimbawa difference between Alberta, Canada o Florida, USA.

Ang quality ng oil ay malalaman lang sa API service class rating na gamit. https://secure.wikimedia.org/wikiped...ervice_classes

Ang mga engine oil ngayon ay multi-use , pwedeng pang diesel o pang gasoline, pero kailangan tingnan ang API class na angkop sa gamit nyong sasakyan.

Ang mga rating sa diesel oil, a CJ-4, CI-4, CH-4, CG-4, CF-2. ang letter C ay para sa compression ignited engine. Mas mataas na send letter, mas maganda ang performance at quality.

Ang para sa gas engine naman ay SM, SL and SJ. Gaya sa taas, kung mas mataas ang pangalawang letra, mas maganda ang quality at performance. Ang letrang ay nangangahulugan na para sa spark ignited engine.

Para sa fuel economy at pag maintain ng engine condition. mas maganda gamitin ang fully synthetic oil. ExxonMobil ang nagproproduce ng fully synthetic base oils na gamit at ang ibang oil company ay bumibili lang sa exxonmobil. Kaya Mobil synthetic oil gamit ko, hehe.
