You can mix normal,semi and synthetic oils together with no loss of lubrication.but on a car of this age normal its fine to use 10/40 if not burning oil and 20/50 if burning over 1/2 quart every will need to drop the underbody splash cover to get to the sump plug,its on the bottom of the oilpan on the lower bulge.

Recommended engine oil for 2004 nissan pulsar 180000 klms

quality brand 20w-40 engine oil
you can use semi synthetic or full synthetic but as the oil should be changed every 10,000miles , it is not the cost of the synthetic oil
remember that the viscosity of the oil will depend on the ambient temp in your operating area so read your owners manual or talk with accredited service centers to help you decide

Which Oil Should I Use?

A common question is 'Which oil should I use?'

There's three categories of engine oil:
  1. Fully synthetic
  2. Semi synthetic
  3. Mineral
As a general rule of thumb, fully synthetic is the best - and the most expensive.
Semi synthetic is a blend of synthetic and mineral oil, and mineral oil is lifted out a hole in the ground in a bucket.

Oil is also given a rating of 0-30W and 5-40W. There's others, of course. This rating just refers to the viscosity - the thickness of the oil under certain conditions. 0-30W is a thinner oil than 5-40W.

At one time people used to use a thicker oil in their car engine during the winter months and a thinner oil during the summer months.

Fully synthetic 0-30W oil is often specified for engines that have 'zero tolerance'. Here, zero tolerance simply means no space between the metal of the piston and the cylinder wall. The oil must be thin enough to be able to coat the mating metal surfaces and yet be robust enough to withstand the pressures of what is basically pressurised metal to metal contact.

Using semi synthetic oil in a zero-tolerance engine will cause very rapid wear indeed. Topping up a zero-tolerance engine with mineral oil can have catastrophic results. Not only does it not afford protection but it - the mineral oil - will form a 'globule' - a ball - inside the oil sump/pan that will block the oil pump pick-up with absolute catastrophic results - very quickly.

In Europe the Saab 9-5 model had, amongst others, a V8 3000c diesel engine fitted. It was a zero-tolerance engine. Many of these cars ended up with wrecked engines simply because owners had topped up with the wrong oil. And, on a zero-tolerance engine the oil level itself is critical so much so that Saab modified the oil dipstick so that owners overfilled with oil by 1 litre. A zero-tolerance engine doesn't tolerate a 'slightly lower' oil level.

Most drivers wouldn't know if their car was a zero-tolerance engine. If you use fully synthetic 0-30W (or follow the manufacturer's recommendation) you won't go far wrong. You can use fully synthetic 0-30W in your 1956 Cadillac if you wish. It won't harm it.

Other grades of fully synthetic are fully suitable for all non-zero tolerance engines.

The difference between fully synthetic (apart from the price) and semi synthetic and mineral is that of durability. Fully synthetic 'breaks down' slower .. in other words, it lasts longer as a 'lubricant' ... does its job better.

Short journeys destroy engine oil - particularly mineral oil. Toxins and carbons accumulate in the oil and cause it to break down into 'sludge'. Semi synthetic oil is more resistant to breaking down, and fully synthetic is even better.

If you've got a decent car with a decent engine - use fully synthetic 0-30W. If it isn't a 'zero-tolerance' engine use any fully synthetic oil or semi synthetic oil.

If you have an old 1998 4 litre Jeep that burns oil like I have, a cheap mineral oil will do. But do change the oil and filter regularly. Regular oil/filter changes promotes the life of your engine - irrespective of what car you drive - and it really does prevent mechanical problems such as noisy camshafts/engine knocks.

What is the best oil to use in a 2001 lincoln navigator

There is no best

You use the brand you prefer

You use the type you prefer

What you may be asking is,what grade or weight oil?
It should be in your owners manual,on the oil fill cap,

Most Fords use 5W-20 ,yours may use 5W-30.

I would use Mobil 1 5W-30 ,if 30 is correct
Avail at wal-mart and expensive

I need an oil change for my '07 passat sedan and I'm not 100% sure if I should use 5W-30 or 5W-40.

Look at you owner's Manual and it should tell you. and sometimes it also say on the Valve cover Cap where you put the oil in. Good luck

Hi im at work on my own in a car tuning workshop! i have a 1990 mazda mx5 track car on the ramp, standard 1600cc engine as far as i can tell, and the owner has told me to be sure to put exactly the right...

It calls for a SG rated 5w30, or 10w30. so a synthetic will be far superior, just use the best oil you have. It it works hard at hot temps, use 10w30

I bought a 2002 Galant with no owners manual. What type of OIl does it take? And what is the correct tire pressure

I would recommend penzoil 5-30 oil. Clean and leaves less gunk. It looks clean in the intake manifold and the Fuel injectors as well as the general performance is good. Compared to other oils and costs, it's a good oil.
For synthetics, use 10-W30 Castrol pure synthetic is really good, so is Mobile 1. Also combine that w/ a Bosch oil filter.

Trying to find out what grade oil to use for my 2001 VW new Beetle 2.0L GLS

5W30, or 10W30 semi synthetic. Unless you use a long life oil, then its 0W30 full synthetic with VAG spec. 503.00
If only topping up, then use a 5 or 10W30 semi synrthetic
Hope this helps

What oil should i use for my W reg ford fiesta finesse 1.3

You can use either a full synthetic blend oil 5W30 or 5W40, and even a semi synthetic blend oil 10W40.
If you have the last invoice for service , it should state which grade of oil was used, or you can check under the bonnet to see if they put a service sticker or tag , showing which oil they used.
Hope this helps

2002 honda civic LX oil change

A synthetic is good if you don't mind going 15 to 20,000 miles between changes. If you're one of the compulsives that change oil every 3000 or 5000 miles, don't bother with synthetics, because they're expensive. You probly need a thinner grade of oil, tho, like a 5-20. Thinner grades will help your gas mileage, but check your manual.
