I believe so, its the Mazda brand Syn oil w/moly that the dealer uses. I do about 13-14k miles per year so I'll probably keep my OCI's at every 6 months. I think 7k miles is the most I'd want to put on the oil despite Blackstone saying that I can do 7500. Has anyone else posted a UOA on a...

I basically use the cx-5 as a commuter car, 70 miles roundtrip a day with 80% highway and 20% city driving. Never revved past 4k RPM.

Hey folks just wanted to post the results of my UOA on my 2013 Mazda CX-5 (gasoline 2.0L)

Yep I checked some of the pcv hoses they are caked in oil, valve cover gasket has oil all around the edges. Keep in mind I had the pcv valve, breather hose, check valve, upper/lower hoses replaced about 40k miles ago. I think the ARX might have amplified the problem. Can I simply replace the...

Yea I've used T6 extensively on the Jetta but switch to M1 OW40 during the winters. So do you still get bad oil consumption?

Car: 2001 VW Jetta 1.8T with 153K miles , I'm about 2400 miles into my Auto-RX cleaning phase cycle. I used the fast track program which involves 2 bottles of ARX in conjunction with Rotella T6 5W40. So far: I have changed the oil filters twice in the last 2K miles (1 filter change per 1K...

bumping this again, just wanted to see if there are any VW 1.8T owners out there who have tried this on their cars. I have a bottle in hand and am considering dumping it in prior to my next OC. THans!

Yes I'm not sure what to make of the reports given the multiple top-offs. I am still in the process of trying to find out if the oil is either: 1) Getting burnt up in the turbo 2) Leak somewhere (But I dont see puddles of oil in the garage) 3) I need a valve ring job (No smoke blows out of the...

2001 VW Jetta 1.8T Wolfsburg Edition w 134K miles. Oil sampled after 4,450 inside engine Topped off 3 times , it burns about 1qt every 800-1000 miles.

Ok, Wanted an opinion from the folks who use Rotella on non TD cars. I've had the Rotella 5W40 in my 2001 Jetta 1.8T for about 5k miles now. I know from the get go that this is a non 502.0 approved oil but a lot of the VWVortex forum members love this oil (not just the diesel guys) so I...

wolf: Thanks for the tip but I think I may stay away from ARX for now until as it seems this motor just eats up any kind of oil. I just switch the Rotella 5W40 Syn and am seeing pretty good results (see below) Bugzii: See below =) My PCV system is fine as I replaced the upper/lower hoses last...

Hey guys I just took a sample and will be sending it in to Blackstone for analysis. John: You mentioned that the Z & P would have to burned in the commbustion chamber for it to be expelled into the cat. Given the fact that my Jetta seems to already burn oil - could this already be happening...

Just wanted to report back that I've put about 1300 miles running Rotella and have since added an additional quart of oil to top off the 1qt that I burn. (total of 5 + 1 qts oil used) I checked the level this morning and noticed that it's back down to the low level on my dipstick. Meaning...

I recently added Rotella Syn 5W40 to my 2001 Jetta 1.8T . I have read that due to some additive/detergent in the Rotella that I risk clogging my cat. Now has there been any documented evidence/proof that this has happened to anyone? I'm loving the price/reviews on Rotella but am concerned with...

The oil pickup tube was replaced at 104k miles when I first brought the car. The oil pan and valve cover had varnish indicating the previous owners either were not keeping up with regular OCI's and probably used fossil oil. The pickup tube didn't have any debris but the varnish is indicative of...

mechanicx: My original intention was to switch back to dino oil and shorten my OCI's to every 2.5k miles (I have a Mityvac vacuum) Else, I don't have any engine knock issues at all. Gary: Thanks for the advice, the Jetta is a DD so I drive it very conservatively. My play car is a S2000...

Hey everyone thanks for all your comments, just to add some additional details. This is the bottom of the report I forgot to include: Background on the Jetta: -I am the third owner of the car. It was purchased with 104k miles and now has 125k. (Owner 1 had it for 90k Owner 2 had it for...

Hi first post here, but wanted to post the details of my oil analysis report today and I am quite alarmed at the high copper and lead content of my AWW engine. Because my Jetta consumes almost a qt of oil every 1K miles I just started using fossil Valvoline 5W30 oil to keep costs down and also...
