I have 88crx with smoking issue, any suggestions on best oil and or additive to use. only 90,000 miles on engine. thnx

 

I use BG MOA oil additive and just 10w30

 

not familiar with bg moa .

 

I use Q horse power in my 89' Prelude Si. I felt a difference when I went to Castrol Synthetic. When I changed from that to the Q horse power, I felt even more improvement.

My 89' Z24 with a 3.1 smelled bad after I drove it hard. I used the Q horse power, and now the is no smell. I've also herd Royal Purple is a good oil.

When it comes to additives you really don't need it using an oil such as Q horse power. When I was using Castrol Synthetic I used Slick 50. I could feel the difference with it as well. I done tire a lube for a while. The most preferred additive was the Lucas.

As for as it smoking, your rigs may be bad.

Slick 50 was proven to not work enough that there was a class action lawsuit. The FTC also said they could no longer claim any performance benefits in their advertising/packaging.

Additives, as a general rule of thumb, are crap.

Just about any synthetic is going to perform lubrication duties better than conventional.
With a leaking/burning engine condition, the expense of synthetic is hard to justify. It may even exacerbate your problem.

Stay away from the premixed semi-synthetics...many companies do not disclose the ratio of synthetic to conventional. Technically, they could put 10% synthetic in there and double the price.

Independent lab tests on conventional oil are published on a frequent basis. The results tend to fluctuate a bit, but Castrol and Valvoline consistently do well. They both produce a "high mileage" formulation that are supposed to resist burn-off. I can't say from personal experience that they work, but they're out there.

 

You can get it at any dealership? but yes royal purpel is good too i used it in my trans and have done a couple oil changes with it and also lucas oil stabilizer i ran it in my subaru it stops the lifter noise. Q state syn blend its free to me

 

thanks for the info. Ill stick with conventional castrol and try some lucas and see what happens from there. by the way, anyone try the engine restore stuff, already bought a can but havent put it in yet.

 

Fix whatever is causing it to smoke and run whatever oil you want.

just grab a new dseries motor for like 50 bucks, any local speed shop should have a couple d15's laying around.
