Oils for taxicabs

[hitechchef]

Hi, I drive a cab. Summer temperature +30C winter -20. My chevy uplander has 165000 km. I am using Valvoline Maxlife 5W30. But my engine burns a lot of oil. Almost 40% for every oil change at 10000 km. Is this normal. Should I change oil brand or grade. Any suggestions are welcome.

Try to add tcw3 oil in the gasoline each tank at ratio of 500:1.

It will clean the rings and increase the compression.

No, that's not normal. Check your PCV system.

You're out of warranty, so try a 15w40 HDEO during the summer months. If that helps, use a 5W-40 during the winter.

Assuming it's rarely shut off, or stored in a heated shop when off, he could get by with 15w40 all year. For cabs, I've used 10w30 all year, for many, many years. They're never turned off in the cold, and we get far colder than -20 C.

What if he does want to turn it off?

There was another canadian cabbie on here who ran Esso fleet 0w30; IIRC they also make a 0w40 that would be great for you year round. But expensive, you could do 15w40 summers as suggested.

 

[addyguy]

A good deal, so you don't have TOO much oil on hand is the 9L jugs of Rotella 15w40 sold at Walmart for like $36.

Continue with the MaxLife, and use a product named Restore. Although I don't generally use additives, Restore has proven effective with vehicles in situations similar to yours. It has helped mine in the past.

It was "Olympic" and he can be found in the great hockey province of Saskatchewan

. Here is an example of a stellar UOA of one of his Pontiac Montana taxis using XD 0W30.

Too bad Olympic isn't here anymore.

Those used oil analysis threads were great!

Yes, just there you have to stay.

Good luck.


dont even bother, it does not last long.

 

[gfh77665]

Use it each OC time and it will. It did for me.

 

[Gary Allan]

Does the consumption cause other issues? Does the engine smoke at all? Do the plugs foul? Any loss of power or reduction in fuel economy ..or rather increase in fuel consumption?

I'd also agree that you're operating much more at normal temps and that start up would not be the primary determining factor of oil viscosity selection. Use a pan heater/block warmer.

..and YES ..check your PCV system for proper function.

How So has Restore helped?

I too believe in this stuff, to a Limited extent.. Ive had FAR better luck with "Lucas Stop Leak." It actually IXED a Ford Escort.. Now This is TRUE!!!

I almost feel like i coulda Kept that car... I dont think i wanted to....

I also "Kind of "f eel like putting "Some" in with Oil every 20-50k miles will help prevent Failures......

Of (Dare i say it) .. Gaskets... along with Blue Devil or Steel Seal.....

Well, he certainly can.

It's really not an issue unless it's stored outside on a -40 night and no one's driving it. Shutting it off for a few minutes between trips isn't going to cool the oil to the point where 15w40 vs. 5w30 is going to cause a huge issue.

 

[hitechchef]

I should have mentioned it. This is 2005 model, 3.5 litre front drive. Also it is running on propane. It remains shut off from 7pm till 5 am.
