Motor Oil

**raine** · March 30th, 2005 07:24 PM

Im planning na magpachange oil, gusto ko sana subukan ang synthetic oil but ang engine ko ay medyo luma na at nabasa ko sa ibang forum na hindi adviseable gumamit ng synthetic oil sa lumang engine kaya sa mineral oil na lang ako. Anong mineral oil ang magandang gamitin and what brand and price? Meron akong nakita na VALVOLINE XLD MULTIGRADE SAE 20W-50 API SG/CD MOTOR OIL (114.45PESOS PER LITER) IN BLACK PLASTIC CONTAINER. MADE IN USA. Maganda ba ito? Meron na ba kayong comments sa price mahal ba? Sa mga kaibigan natin sa US maganda ba ang oil na ito ng VALVOLINE?

It's safe to use synthetic oils on old engines as long as:
- you don't have oil leaks (too expensive to keep topping up)
- the engine does not consume oil
- use quality oil filter, orig or Vic
On mineral/ synth oil, try to get one with the latest API rating-SL. The Valvoline's API SG is 3 levels lower.

You can use synthetic, make sure that its thick enough so that it won't leak. Check your manual for the API rating. BTW Whats your car?

API rating generally refers to the standards set by the American Petroleum Institute for oil quality (well... something like that). The higher the API rating (in alpha-numeric), the better supposedly the oil is, especially for newer engines. CMIIW.

The higher ones nowadays is CI-4 for diesel oils and SL for gasoline engine oils.

The Valvoline you're looking at is already dated based on it's API ratings, you can try checking out other mineral based oils like Petron Touring (SJ or SL) 20W-50. Higher viscousity oils are recommended for older/high mileage engines and for hot/humid weather climates.

If you're on a budget (well nowadays who has the luxury of extra cash?), it's still better for your pocket and your engine to stick to regular oil then change regulary (every 5,000km).

Suggest using newer API oils, like SL/ SJ for your civic '96. If using synthetic oil, a thinner grade like 5w40, 10w30 is still ok since the oil won't burn in normal use. If you opt for mineral oils, then start at 15w40, 10w40 to give enough leeway to handle heat stress on the oil.
There are some diesel oils that are rated for both gas and diesel use, ie, API CI/SL so safe to use on gas engines too.
Check out Conoco Super J, 15w40, Api SJ/CF- about P420/gal.
