I have this issue where the Engine burns the oil quickly and I have to fill it will oil weekly. My last oil change service was at American Lube Service about 2 months ago and I asked the mechanic to check on this problem. He told me that there is no leakage and it could be that my car is an older model with high mileage. I'm currently at around 130k. They recommended to go with 10w 30 for high mileage engine. So ever since then that it what I buy as opposed to the 5w 20 which is used for this engine. Any ideas why this is happening?

 

Any other issues drive wise? How much oil are we talking a week? Any smoke coming out of the tailpipe. Sometimes you will only see it under hard acceleration or with the VTec kicks in.

Have you pulled and checked any of the plugs. I will bet you would find one or two with signs of burnt oil. That could be a ring letting some oil pass.

If you pull the plugs and find one or two with signs of oil burning I would do a compression test. That will give you a better idea of how each cylinder is doing.

 

Do not use 10W-30 regardless of what that clerk told you.. 5W-20 or 5W-30 is what you should be using I am at 218K and still use 5W-30 and don't have to add a drop between oil changes.
Burning oil can be caused by a valve PCV valve as well.

 

With that mileage I seriously doubt the engine is burning a significant amount of oil, unless it was badly abused (run on low/no oil for an extended period of time). I have 207K and I am about a quart low after about 4-5K miles, but my oil pan gasket is also leaking (and maybe also the oil pump gasket). I'll deal with adding some oil in between changes until I feel like tackling the gaskets... ugh.

+1 to the above... check plugs, compression test, check PCV valve.

 

You might have stuck rings. Mine are, tried everything to fix, but no luck. Check your plugs, compression can help, but won't diagnose stuck oil control rings.

 

No other issues. I'm not sure but I buy the 1 Qt and pour about 2 of them weekly when I'm slightly below the first line. 3 and 1/2 when oil is barely shown. I haven't seen smoke coming out of tailpipes. How can I check the plugs? Where are exactly?
Compression test can be done where? Any mechanic shop?

Ok I will switch back. Is there one for high mileage or will it make a difference if I get the regular? I didn't see one for 5W-20. There is one for 5W-30.The engine takes 5W-20.
Is it expensive to have the PCV valve checked?

Not badly abused. However this issue has been going on since more than a year if I recall. But never this bad where I'm pouring oil in the engine weekly. This process began sometime the start of this year give or take.

 

Ok so now my my car has new issues. The engine light and VSA is on. I also have slight vibration at idle. Dealer performed the test and found out that the engine could be done. 90% sure but is doing the compression test. If not the engine it could be the rings. Don't remember which ones he told me. I don't know what to do now if it is the engine. I'm not going to spend $$$ on a new engine. I already replaced the original engine with this one.

Your thoughts?

 

If the engine is done there isn´t much we can tell you, You only have 2 options..
1.- Get a J35A3 from the MDX
2.- Part ways with the car
or
Optional 3.- Rebuild the Engine (Which is none-sense since its stupid expensive).

 

130,000 miles on this engine or on the car which is on it's second engine? Either way, that's not a lot of mileage for a Honda engine. Probably not worth fixing the car if that's the case. Might look to part it out.

 

You could just try to find a good low mileage engine from another TLs and swap it in, The used engines for these are pretty cheap
