I changed the oil and filter but the oil turned dark within 50 miles of driving. Is there any recommended ways to clean the engine of deposits before I change the oil again?

SJC

pull oil pan, check it out. other then that make sure the oil is completely drained before you put in the new ****...

Drain it and re-fill it again.

seafoam or get a motor flush from autozone .

HONDA1luv

what about those Gumout engine flush they sell???
id imagine that coould help with your problem. throw that thing in before you do your next oil change it should clean it out

It got dirty bc all the oil that is left in there. No way to get all excess oil and gunk out of the motor with a simple oil change you either need a flush or buy some cheap oil if your that concerned and change the oil a few times within 50-100 miles of eachother and that could help.

The main ingredient in most engine flushes is kerosene. You could add a half quart or so to the oil and let it idle 5 to 10 minutes, then drain and refill. If it concerns you this much , pull the oil pan and clean it thoroughly with Purply Stuff. If you are careful, the original pan gasket can be reused if it is in good shape. If both surfaces are clean and dry, you should have no leaks.

I'd do multiple serial oil/filter changes prior to any flush. In fact, you may want to avoid a flush if it's a high mileage engine.

What intervals should I use?

Former User

Off the top of my head, I'd say 200-500 miles.

Same thing happen to me in my LS Del Sol i did a oil change witch i used and OEM oil filter and about 2 weeks later witch i easily can put 350 - 400 miles on it and when i checked the oil it was hella black like 3 months use

would this be cuz my Del Sol is running rich ? cuz i know it is and i know i need a tune

What kind of oil do you use - mineral or synthetic?
What kind of oil filter?
How many miles have on the engine?

The oil gets dark immediately after a few miles it depends how dark.
Try to flush first with synthetic oil and K&N filter.
If it doesn't help try with kerosene. Make a research how to do it before flushing with kerosene.

Oil is Pennzoil 10w40 mineral "only and always"

filter OEM Honda

Miles on Block dont know

last time i changed the oil it stayed clean for 3 months so next is a flush i guess

It's definitely a product you want to follow directions using.

I have a buddy who flushed all his cars. I never flushed. He has now Lexus ES300 and Audi A4 (turbo). He recently flushed the Audi with kerosene. The engine should work only on idle for about 5-10 min. I would go for 5 to be save. You can flush with diesel fuel too. The kerosene has a octane grade somewhere b/w 87 gasoline and diesel. Kerosene actually is jet fuel.
Some guys with diesel engines put little kerosene in the tank during the winter to prevent freezing of the diesel fuel.
Some people say the kerosene is no good for the gaskets.

p.s.
Why don't you drive with 5W30 oil I think is recommended by Honda for most of the Civic engines?

Josueneta

cuz i have a B18a1 a 93 iv always bin told to use 10w40 since it older and cuz its got miles on it but maybe i bin wrong i should use 10w30

Safety_Driver

If your engine does not burn a lot of oil I would go with the thinest oil, which is 5W30. Inthe summer my use 10W30. I always run with 5W30 in the winter, bc the temp. here drops to 4°F.

Honda manual (specs for D15B7 and I belive for all Civic engines):
“An oil with a viscosity of 5W30 is preferred for fuel economy and year-round protection. You may use 10W30 oil if temp. in your area never goes below 20°F (-7°C).”
