best brand of motor oil?

Answer 1

valvoline

Answer 2

It depends. There are whole web sites devoted to motor oil discussions. The best advice is to use the type of oil that the manufacturer recommends (read the manual), and change it at least as often as the manual recommends. Most American and Japanese cars use 5w20 or 5w30 oil (conventional or synthetic). Many European cars use 5w40 oils (all synthetic). Some manufacturers have oil specs (e.g. MB 229.5, VW 502.00) that are indicated on the oil bottle, particularly if the cars are equipped with oil life monitors or have extended (i.e. 10K or more) oil change intervals. If yours is one, be sure to check for the oil specification on the bottle. As others have pointed out, American and Japanese manufacturers follow the API specs (most oils are now SL or SM, which should work fine if your car uses an older oil, such as SJ). European oil producers follow the ACEA standard, which are A1, A3, A5. Most A1 oils sold here are also A5, but A3 oils meet that standard only (i.e. there are no A1/A3 or A3/A5 oils). Again, check your manual if you have a European car.

As for specific manufacturers, while each has its own blends and additive packs, for the average driver, any mainstream oil that is consistent with the manufacturer's recommendations should be sufficient.

Answer 3

Depends on if for car, bike, truck, airplane; gas, diesel, turbine. Most important: Use viscosity rating and brand that your owners manual / manufacturer recommends, and check/change at recommended intervals. Synthetics can extend your change interval, improve fuel economy, protect your engine against damage during racing, and cosmic rays (not). But synthetics can also cause notchy shifting in some bikes, and oil leaks in older engines. One of my former customers, a good friend, and my brother put over 300,000 miles on engine with regular oil. (Pontiac Bonneville, Toyota Corolla, VW Jetta.)

Answer 5

All major brands produce their oils to meet the API (American Petroleum Institute) standards. Choose the standard specified for your engine, usually the latest works for all gas engines, then pick a brand that is readily available at the price you’re willing to pay.

Answer 6

It depends. Synthetic oil is better but you should't switch to it if your car has been running regular.If you have an older car I highly recommend High Milage oil for it, But I do not have a brand preference as oil is oil no matter what name is on the bottle.

Answer 7

That depends on the application, the full synthetic I run in my car and like the best is Royal Purple.

Answer 8

Castrol is a pretty good brand. It's what I use.

NEVER buy Pennzoil. They put paraffin in it. This will gum up the oil passages in the engine.

Answer 9

i don't think their is a "best" brand anymore
major oil companies make all the oil
for example....napa oil is made by valvoline
do you see my drift???

Answer 10

There isnt one brand that is the best.... but name brands are best to use. I personally use Valvoline Maxlife...... I also like Penzoil.

Answer 11

Havoline or Vavoline
