Car Forum / Honda Cars / February 20055W20 in 2000 Accord?
Hi all, At my last oil/filter change on my 2000 Accord 4 cyl (at the dealer), the invoice indicated 5W20 - service advisor explained that they are using 5W20 now for all years/models. This despite the factory recommended 5W30 for a '2000. I have had my car serviced at the dealer since new on the assumption that they should know the car best - now I am not sure - any opinions? I will insist on 5W30 the next time (as warmer weather approaches!) Cheers, Cameron Tilson Montreal, Qc Canada > Hi all, > [quoted text clipped - 11 lines] > Montreal, Qc > Canada You'll find a lot of threads on this if you search. The current generation of Hondas are using 5W20, and they are recommending this for some older ones now. Some owners are okay with this, and some are ticked off and ignoring the recommendation. The mechanical specs of Honda engines haven't been changed, just the oil recommendation. To get a tenth or so additional miles per gallon. So it should be just as good (or bad) to use 5W20 in a 2000 as in a 2005. Personally, I'd stick with 5W30 or even 10W30 where conditions allow. Only 10W30 has a 6,000 mile/10,000 km lifespan to the oil. 5W30 is less before it starts breaking down, and 5W20 is even less, about 3,000mi/5,000km. So you can use it, but you've gotta keep changing it. IMHO, using 5W20 with a 10,000mi oil change interval is crazy and not supported by actual oil sample testing, but it is the recommendation for current I4 models. JM Over an oil change interval, if the engine's not loosing any oil, I'd go with the thinner stuff. I'm assuming that the 5W20 is thinner then 5W30 and thus flows better at regular operating temperatures. Or, if the engine gets excessive use and/or driven hard, I'd go with Mobe-1 5W30.

Bobistheoilguy.com posts oil test numbers. Mobil 1 0W20 is apparently beating out Mobil 1 5W30 for reduced engine wear. Go figure. JM > Bobistheoilguy.com posts oil test numbers.

Assuming it's changed frequently enough, this isn't really surprising. 0W20 presumably would start flowing through the engine more readily on a cold start, which is when a lot of engine wear occurs. But you wouldn't want to leave it in there too long. You might also consider a low viscosity oil with better high-temperature characteristics, like Mobil 1 0W40, for longer change intervals. -- Mike Smith > > Bobistheoilguy.com posts oil test numbers.

When the weather starts to warm up, I'm planning on changing over to OW40 (instead 5W30). I've increased my oil change interval to 15,000km. Perhaps another car will 'gum-up' the oil too quickly and thus require more frequent oil-change intervals, but after 15000km of use, the mobel-1 oil in my Honda engine is still silky smooth. I've heard that VW's and Toyota engines are susceptible to gunk build-up and in those cases, frequent oil changes would be a necessity. Note: I only use Honda's air filter and oil filter (Forced intake and performance air filter will cause the oil to become more dirty, more quickly).

With the VWs, it's really only the 1.8T that has that problem, as opposed to the normally aspirated engines; as a result, 5W40 is recommended. -- Mike Smith > > I've increased my oil change interval to 15,000km.

That's too bad. Hopefully, VW's got the problem beat with there new 2.0T. My friends 1999 1.8T Passat has over 220,000 miles and he's had the oil pump replaced twice (the first time was under warranty). The engine/car still kicks butt, but it's costly to maintain (His Passat is a sweet setup with 5sp, leather and sunroof).

Maybe--MAYBE--they can show you a Honda bulletin that shows 5W20 oil is approved for your car. IF they can, that's good news, and I wouldn't worry about it. But more likely, they want to cut costs by carrying only one type of oil. Too bad, so sad, they're losers, you should lose them. |
