questionns about oil,

That comes with the filter, don't look at it and think it's probably just a spare :D

Depends on the brand of filter you buy.

Fram and G.U.D normally have them.

Donaldson, Fleetguard and Baldwin do not have them.
 
Unless you own a rotory the price of the oil doesn't matter assuming it's the correct spec. But that's just my opinion.
 
Hi

Goldwagen is cheap on oils.

6 x 500ml oil tins will most likely cost you more than a single 5L can from a Midas or Autozone.

Autozone has a special on Shell hx 5 atm

Any name brand oil of the correct spec will be fine.

Shell Hx5 5w40
Castrol
Valvoline

Not true. Cold start and engine operating viscosity has little to do with ambient temperature.

Ambient temp has every thing to do with choosing the correct viscosity engine oil. My car service manual lists different oil depending on climate

Only for cold start. Operating temperature is pretty stable all over the world.

Thanks silver, so should I buy a big 5l oil bottle, or smaller tins, and make up the difference?
Or is it better to buy 500ml tins and make it up that way? What works out cheaper?

That's what I'm trying to work out?

Also mixing of different brands, some say no some yes.
In other words, if my remainder of my 5l is shell, and I buy castrol or Valvoline or others, will it be bad for the engine by mixing?

If the oil is pretty much same spec level, is it bad if I mix?

Saw that carbible article, and it says it's fine. But wanted to know from you if it's safe.

I haven't read the whole thread, I must confess.

It's probably not particularly problematic to mix oils of the same spec (eg 20w50).

Personally I won't do it, because manufacturers use different formulations for the various additives engine oil requires, such as detergents, anti-foaming agents, etc. The shearing forces oil is subjected to are huge, and I'd worry that the additives in the two different oils could interact in a way that reduces the oil's overall performance or affects its carefully crafted chemical balance so it doesn't corrode various metal surfaces inside the engine. The main purpose of oil is to remove heat from certain hotspots, and I'd worry this is less then optimal, kinda like mixing blood types - 98% the same stuff, but the 2% can cause interaction probs. This concern is greatly exaggerated, but it lurks at the back of my brain.

That's why I ask people in SA, and on mybb who might know better
Still trying to decide if I should stop driving people mad, and just get a new 5l and be done with it, although don't know if it's cheaper?

Just get another 5L of the same brand you already have, then you have peace of mind, plus you'll have oil left for the next change.

The only things you don't want to mix is fully synthetic with pure mineral.

You want to mix semi-synthetic with either, or mineral with mineral, or fully synth with fully synth.

Even worse case if you were to mix different viscosity's it would be better than mixing different types.


As was said above, just go buy more of the same oil you have already and then you don't need to do any guessing. Bigger bottles are always cheaper per litre, but obviously buying less litres will be cheaper in your case so buy some cans.
